Answer:
First point goes on -2
Step-by-step explanation:
Answer:
<h3>Part A</h3>
<u>4 CD's cost $30.40, so one CD costs:</u>
- 4p = $30.40
- p = $30.40/4
- p = $7.60
<h3>Part B</h3>
80% of the regular price is $7.60
<u>If the regular price is r, we have:</u>
- 0.8r = $7.60
- r = $7.60/0.8
- r = $9.5
<u>3 CD's at regular price cost:</u>
Since $25 < $28.5, we can't buy 3 more CD's.
<h3>Part C</h3>
she uses the same amount of fruit so Susan used 5 strawberries per cup ( 5*5 = 25 total strawberries) and 3 kiwi ( 3*5 = 15 total kiwis)
25+15 = 40 total pieces of fruit.
Joanna made 4 cups with 8 strawberries each
8*4 =32
40-32 = 8 , so she can use 8 kiwis
8 kiwis / 4 cups = 2 kiwis per cup
