Question

The cost of a gallon of gas increased from $3.54 to $3.87 over the weekend. What is the percent increase for the cost of gas, rounded to the nearest whole percent?

Answer 1

Answer:

9%

Step-by-step explanation:

percent increase is calculated as

$\frac{increase}{original}$ × 100%

increase = $3.87 - $3.54 = $0.33 , then

% increase = $\frac{0.33}{3.54}$ × 100% ≈ 9% ( to the nearest whole percent )

Answer 2

Answer:

9 %  (rounded to the nearest whole percent)

Step-by-step explanation:

the amount of increase:

3.87 - 3.54 = 0.33

Then

the percent increase for the cost of gas :

$=\frac{0.33}{3.54} \times 100\\\\= 0.093220338983 \times 100\\\\=9.3220338983 \ \%$
