Question

The spring the owner of a sporting good store decreases the price of winter gloves from $10 to $8 each increases the price of swimming goggles from $8 to $10 without doing the math you think the percent decrease in the price of the gloves the same as the percent increase of the goggles explain why or why not

Answer 1

for gloves

`(1 - (8)/(10) )* 100 = 20\%`
for goggles

`( (10)/(8) - 1) * 100 = 25\%`
so they have not changed by the same percent
