After a year of weight training, Harold's weight changed from 172 pounds to 185 pounds. What is his percent increase in weight to the nearest tenth

70.2%

Step-by-step explanation:

Given data

Initial weight =172 pounds

Final weight = 185 pounds

% increase= Final - Initial / final  *100

% increase=185 - 172 / 185 *100

% increase= 13 / 185 *100

% increase=0.0702*100

% increase=70.2%

Hence the increase is 70.2%

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
