Question

calculate the percent change in restaurant expenditures from march to april.

expense	march	april
water	$50.00	$52.00
groceries	$110.00	$125.00
restaurant	$100.00	$85.00

round to the nearest whole percent.

Explanation:

Step1: Identify initial and final values

Initial value (March) = $100.00, Final value (April) = $85.00

Step2: Use percent - change formula

Percent change = $\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times100\%=\frac{85 - 100}{100}\times100\%$

Step3: Calculate the numerator

$85−100=- 15$

Step4: Calculate the fraction

$\frac{-15}{100}=-0.15$

Step5: Multiply by 100%

$-0.15\times100\%=-15\%$

Answer:

$-15\%$
