A one month supply of multi-vitamins is $28. A two month supply is $49. How much money can a customer save by going with a two month supply?

By going with a two-month supply, the customer can save $7.

Step-by-step explanation:

Two one-month supplies at $28/mo would cost 2 ($28) = $56.

A single two-month supply would be $49.

By going with a two-month supply, the customer can save $7.

A customer can save $7.

To get two months of the one month supply, you multiply it by 2.

$28 x 2 = $56

To find the difference (how much you can save) subtract $49 from $56.

$56 - $49 = $7
