Answer:
Step-by-step explanation:
<u>Given:</u>
- Quarter = 25 ¢, number of quarters = q
- Dime = 10 ¢, number of dimes = d
- Total amount = $13.20 = 1320 ¢
<u>Required equations:</u>
- q + d = 72
- 25q + 10d = 1320
<u>Solve by elimination, multiply the first equation by 10 and subtract from the second equation:</u>
- 25q + 10d - 10q - 10d = 1320 - 10*72
- 15q = 600
- q = 600/15
- q = 40
<u>Find p:</u>
- 40 + p = 72
- p = 72 - 40
- p = 32
88= 2l + 2w
l=3w
88=2(3w)+2w
88= 6w+2w
88=8w
w=11
l=3(11)
l=33
width= 11
length= 33
