The sales of a particular brand of children’s athletic shoes rose from 6900000 to 7500000. find the percent of increase in sales. round to the nearest tenth of a percent if necessary

6900000 + (6900000 * x) = 7400000

This equation is telling us 6900000 plus 6900000 times a specific percent will get you 7400000, which is what you want.

6900000 + (6900000 * x) = 7400000

6900000 + 6900000x = 7400000

Subtract 6900000 from both sides.

6900000x = 500000

Divide both sides by 6900000

x = 0.0724637681, or .07 when rounded to the nearest tenth.

convert .07 to a percentage by moving the decimal point two places to the right.

.07 = 7%

The sales of the children's athletic shoes rose about 7%
