Question

1. a company made $800 one week and $900 the next. what was the percent increase?

Explanation:

Step1: Find the amount of increase

$900 - 800=100$

Step2: Calculate the percent - increase formula

Percent increase=$\frac{\text{Amount of increase}}{\text{Original amount}}\times100\%$
Substitute the values: $\frac{100}{800}\times100\%$

Step3: Simplify the expression

$\frac{100}{800}\times100\%=\frac{1}{8}\times100\% = 12.5\%$

Answer:

$12.5\%$
