a factory could make 84 toy robots in one day. they purchased some new equipment, and can now make 105 toy robots in one day. what is the percent change? ?%

Answer

Explanation:

Step1: Find the amount of change

The original number of toy - robots made per day is 84, and the new number is 105. The amount of change is $105 - 84=21$.

Step2: Use the percent - change formula

The percent - change formula is $\text{Percent Change}=\frac{\text{Amount of Change}}{\text{Original Amount}}\times100%$. Substitute the values: $\frac{21}{84}\times100%$. Since $\frac{21}{84}=\frac{1}{4}=0.25$, then $0.25\times100% = 25%$.

Answer:

25%
