Question

Which of the following scenarios represents the smallest percent change?

A. A baby that weighed 6 ¼ pounds at birth now weighs 8 pounds.
B. A painting that was originally purchased for $650 now has a value of $875.
C. The sale price of a new computer is $599. It was originally priced for $700.
D. After 3 months of working out, a woman that previously weighed 163 pounds now weighs 150 pounds.

Answer 1

The smallest percent change is in scenario C, where the computer's sale price decreased by 14.4%.

Step-by-step explanation:

The smallest percent change can be determined by calculating the percent change for each scenario and comparing them. The formula for percent change is:

Percent change = ((New value - Original value) / Original value) * 100%

Let's calculate the percent change for each scenario:

A. For the baby's weight change, the percent change is ((8 - 6.25) / 6.25) * 100% = 28%.

B. For the painting's value change, the percent change is ((875 - 650) / 650) * 100% = 34.6%.

C. For the computer's sale price change, the percent change is ((599 - 700) / 700) * 100% = -14.4%.

D. For the woman's weight change, the percent change is ((150 - 163) / 163) * 100% = -8%.

Therefore, the smallest percent change is in scenario C, where the computer's sale price decreased by 14.4%.
