Question

Mr. Henry spent $15 on a new hat this week. He learned that the same hat available on sale at $12 last week. What was the percentage increase in the price of the hat this week?

Answer 1

$Price \: of \: a \: hat \: last \: week = \ 12$

$Price \: of \: a \: hat \: this \: week = \ 15$

$Increase = \ 15 - \ 12 \\= \ 3$

$Increase \: percentage\\ = \frac{increase}{last \: week \: price } \times 100 \\= \frac{3}{12} \times 100 \\= \frac{100}{4} \\= 25\%$

Therefore .,

$\red{ Increase \: percentage \:of \: the\:week }\\\green { = 25\% }$
