ANSWER BOTH!!!
brilliants [131]

Answer:

  • A = $52.00
  • B = $6.30

Step-by-step explanation:

<h3>A. How much Bill paid AFTER the discount.</h3>

Step 1: Convert the discounted percent to decimal

20% = 0.2

Step 2: Multiply the discount to the item regularly priced

0.2(65.00) = 13

So, Bill received a $13 discount, therefore, the amount he paid AFTER his discount is:

Step 3: Subtract the result (the discount Bill received) from the regular price

$65.00 - $13.00= $52.00

Therefore, Bill paid $52.00

<h3>B.  The price of the pillow in the department store.</h3>

Step 1: Multiply the wholesale price for a pillow by the marked-up the wholesale price

$4.50 × 40% = 1.8

  • Set up a fraction

\frac{4.50}{x}=\frac{100\%}{40\%}

  • The reciprocal of both sides gives

\frac{x}{4.50}=\frac{40}{100}

x = 1.8

Step 2: Add the result to the wholesale price for the pillow

4.50 + 1.8 = $6.3

Step 3: Round to the nearest cent

Add a zero behind the result = 6.30

Therefore, the price of the pillow in the department store is $6.30
