Question

A hat is on sale for h dollars. The regular price is 7 times as much. Charlie has enough money to buy two hats at the regular price. How many hats can charlie buy at the sale price

Answer 1

Charlie can buy 14 hats at the sale price

Explanation:

Let

h ----> the sale price of the hat

x ---> the regular price of the hat

we know that

`x=7h` ----> equation A

so

Two hats at the regular price is equal to multiply 2 by x

Multiply by 2 equation A both sides

`2x=(7h)*2`

`2x=14h`

2 hats at the regular price cost the same that 14 hats at the sale price

therefore

Charlie can buy 14 hats at the sale price
