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?

Answer :

Harold's percent increase in weight after a year of weight training is calculated by finding the difference between his final and initial weights, dividing by the initial weight, and multiplying by 100. Rounding the result to the nearest tenth, Harold's weight increased by 7.6%.

To calculate Harold’s percent increase in weight, we start by determining the change in weight and then divide that by the original weight. Finally, we multiply the result by 100 to get the percentage.

First, let’s find out the weight change:

Weight change = Final weight - Initial weight

Weight change = 185 pounds - 172 pounds

Weight change = 13 pounds

Next, we'll calculate the percent increase:

Percent Increase = (Weight change / Initial weight) × 100

Percent Increase = (13 pounds / 172 pounds) × 100

Percent Increase = 0.0756 × 100

Percent Increase = 7.56%

Rounding to the nearest tenth gives us a percent increase of 7.6%.

Answer:

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%
