The sales of a kids sneakers rose from $3 billion to $3.8 billion. Find the percent of increase to the nearest whole percent?

100(0.8 / 3) = ______ %

27

Right. 27%

To find the percent increase, you need to calculate the difference between the two values, divide it by the original value, and then multiply by 100%.

In this case, the original sales were $3 billion and the increased sales were $3.8 billion.

The difference in sales is calculated as:
$3.8 billion - $3 billion = $0.8 billion

To find the percentage increase, divide the difference ($0.8 billion) by the original value ($3 billion) and multiply by 100%:

($0.8 billion / $3 billion) * 100% = 0.266667 * 100% ≈ 26.67%

So, the percent of increase in sales is approximately 26.67% to the nearest whole percent, which is 27%.
