One-coat paint costs the most per quart.

Step-by-step explanation:  

We have been given the prices for glide paint, smooth paint and one-coat paint.

To find the paint that costs the most per quart we will have to figure out price of each paint per quart.

1 gallon= 4 quarts.  

Therefore, the price of glide paint is $7.23 per quart.

Therefore, the price of smooth paint is $7.58 per quart.

1 pint = 1/2 quarts

4 pints=4/2 quarts= 2 quarts.

Therefore, the price of one-coat paint is $7.5 per quart.

We can see that price of smooth paint is highest per quart ($7.58), therefore, one-coat paint costs the most per quart.
