1. Which is greater 25% of 90 or 28% of 82.

Answers

Answer 1

Answer:

28% of 82

Step-by-step explanation:

25% of 90 is 22.5

28% of 82 is 22.96

Answer 2

It should be noted that 28% of 82 is greater than 25% of 90

The value of 25% of 90 will be:

= 25% × 90

= 25/100 × 90

= 0.25 × 90

= 22.5

The value of 28% of 82 will be:

= 28% × 82.

= 28/100 × 82

= 0.28 × 82

= 22.96

Therefore, we can see that 28% of 82 is greater than 25% of 90

18(x + 1) = -54 pls help solve this...​

Answers

Answer:

x = 71

Step-by-step explanation:

18(x + 1) = -54

to start off, subtract 18 from both sides

18 - 18(x + 1) = -54 - 18

that should give you

x + 1 = 72

(its safe to take out paranthesis from problem by now) now take away 1 from each side

x + (1 - 1) = 72 - 1

that should give you

x = 71

Let c represent
I

Answers

Answer:

Number of Roses sold = 132

Number of Candy Grams sold = 85

Step-by-step explanation:

Let the number of Roses sold = [tex]r[/tex]

Let the number of Candy Grams sold = [tex]c[/tex]

Cost of one Rose = $1.50

Cost of [tex]x[/tex] Roses = $1.50 [tex]r[/tex]

Cost of one Candy Gram = $2.00

Cost of [tex]y[/tex] Candy Grams =  [tex]\$2.00 \times c[/tex]

Total number of Roses and Candy Grams sold = 217

i.e.

[tex]r+c=217 ..... (1)[/tex]

Total cost = $368

Writing equation as per question statement:

[tex]\$1.50r+\$2.00c=\$368 ..... (2)[/tex]

Using elimination method, let us eliminate [tex]y[/tex] of the two equations.

Multiplying equation (1) with 2 and subtracting equation (2) from it:

[tex]0.50r=2\times 217 - 368\\\Rightarrow 0.50r=434 - 368\\\Rightarrow 0.50r=66\\\Rightarrow r=132[/tex]

By equation (1):

[tex]c=217-132\\c=85[/tex]

So, the answer is:

Number of Roses sold = 132

Number of Candy Grams sold = 85

A caterer charges $275 for 15 people and $425 for 25 people. The cost, y, is a
linear function of the number of people. Write an equation in slope-intercept
form for this situation.

Answers

Answer:

y = 15x + 50

Step-by-step explanation:

We set out by finding the slope

the two points give are (15,275) and (25,425)

Slope m is;

y2-y1/x2-x1 = (425-275)/25-15 = 150/10 = 15

So the equation is like;

y = 15x + b

To get b, let us use the point (15,275)

We have

275 = 15(15) + b

b = 275-225

b = 50

So the equation is;

y = 15x + 50

Which equation could you use to find how long it will take to save for the guitar?
$253.77 + $136.27 = $23.50 w
$253.77 - w = $136.27 + $23.50

The reserve ratio is 20 percent. Households deposit $5000 in currency into the bank and that currency is added to reserves. Recall, to calculate checkable deposits you have to add the original checkable deposits to the new deposit. To calculate required reserves for the deposits, you have to multiply the required reserve ratio (decimal from) by checkable deposits. To calculate excess reserves, you will subtract required reserves from actual reserves.2.1. What level of excess reserves does the bank now have? 2.2. Complete the table below for the Third National Bank. You have to distinguish between a bank's assets and bank's liabilities. The figures in the table below are for the Third National Bank. All figures are in thousands of dollars. (Table/chart/graph) normally goes here)2.3. What is the total assets of this bank? Explain the basics of this banks balance sheet. 2.4.If the required reserve ratio for the Third National Bank is 10 percent, what is the monetary multiplier? (helpful stuff)Recall, to calculate you have to use the formula: Monetary Multiplier = 1Required Reserve Ratio. The money multiplier is a key measure in banking that helps to predict the money supply that will be available to drive economic growth. As you can see from the formula, if the reserve requirement is 20%, the money multiplier will be 1 divided by 0.2, which is 5. We can then use the money multiplier multiplied by the excess reserves to determine the maximum checkable-deposit creation that will be provided by the new money entering the system.2.5. If the monetary multiplier is 4, what is the required reserve ratio? Describe how and identify by what amount the Third National Bank can create money in the economy. (helpful stuff)Recall that, generally, bank creates money in a typical economy by making loans. The Fed sets the reserve requirement (the required reserve ratio) that directly affects the amount of money creation. The Beginning of Change3.
