Answer: Amount of change : $30
percent increase : 200%
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Wholesale price: $15
</em>
- <em>Retail price: $45
</em>
To obtain the amount of change we have to subtract the wholesale price to the retail price:
Mathematically speaking:
45 -15 = $30
For the percent increase, the amount of change (30) is some percent of the original price (15). So:
30 / 15 =2 (decimal form)
If we multiply it by 100, the percentage is:
200%
Answer:
72 sq ft
Step-by-step explanation:
A = l × w
320 = 20w

20 20
16 = w
16 + 16 + 20 + 20

32 + 20 + 20
^ ^
32 + 40
72
The perimeter is 72 square feet.
Hope this helped.
Answer:
16
Step-by-step explanation:
24 minus 8.
The reason I subtract 8 from 24 is because the eight is a <u><em>negative</em></u>. Also, you can do it the opposite way like -8 ADD 24 on so you'll end up with 16 but it's a longer process.
