The sales of a particular brand of children’s athletic shoes rose from $6,900,000 to $7,400,000. Find the percent of increase in sales. Round to the nearest tenth of a percent if necessary.
This equation is telling us 6900000 plus 6900000 times a specific percent will get us 7400000, which is what we 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.
We can 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%
