Question

A pet store increases the price of a bag of dog food by 5%

If the increase in price is $2.00, what is the new price for dog food?

Answer 1

$42.00

Explanation:

We can represent the given information as a ratio:

% of original price : price

5% : $2.00

Then, we can multiply both sides of this ratio by 20 (or 100% / 5%) to get 100% of the original price, which IS the original price.

5% : $2.00

↓ × 20 ↓ × 20

100% : $40.00

Now that we know the original price, we can add $2.00 to get the new price.

$40.00 + $2.00 = $42.00
