Question

calculate the percent change in the electricity bill from june to july.

round to the nearest whole percent.

Explanation:

Step1: Find the difference

$115 - 110=5$

Step2: Use percent - change formula

Percent change=$\frac{\text{Change}}{\text{Original}}\times100\%=\frac{5}{110}\times100\%$

Step3: Calculate the result

$\frac{5}{110}\times100\%=\frac{500}{110}\% \approx 4.55\%$

Step4: Round to the nearest whole percent

Rounding $4.55\%$ to the nearest whole percent gives $5\%$

$5\%$
