12 credits at U of M costs $4,710 and 16 credits at WSU costs $5,218.05. Which school has the cheapest unit price?

WSU

Step-by-step explanation:

Calculate the unit price for each school, then compare them.

The unit price is the price for one credit. To find this, divide the price by the number of credits given at that price.

U of M

$4,710 ÷ 12 = $392.50       <= Keep 2 decimal places for money

It's the same as this:

Each credit at U of M costs $392.50.

WSU

$5,218.05 ÷ 16 = $326.128125     <= Round to 2 decimal places

It's the same as:

We round up because the third decimal place is "5 or more".

$326.128125 ≈ $326.13

Each credit at WSU costs $326.13.

The school with the cheaper unit price is the one with less money per credit.

Since $392.50 > $326.13

WSU has the cheapest unit price.
