Answer:
43. <u>(2) $2.00</u>
Step-by-step explanation:
<u>Question 43</u>
- Let cheese pizza be c and mushroom pizza be m
- 3c + 4m = 12.50
- 3c + 2m = 8.50
Subtract Equation 2 from Equation 1.
- 3c + 4m - 3c - 2m = 12.50 - 8.50
- 2m = 4.00
- m = $2.00
- <u>(2) $2.00</u>
For this case we can solve the problem by means of the following rule of three:
94 --------> 100%
17 --------> x
Clearing x we have:
x = (17/94) * (100)
x = 18,08510638%
To the nearest tenth of a percent:
x = 18.1%
Answer:
This is 18.1% of his compact discs.
