Explanation:
come on !
he writings still have bought 32 oz of paint but in 4-oz jars and for the 4-oz jar price.
so he would have had to pay
$0.73×32 = $23.36
for the 32 oz of paint.
what is missing in the whole question is how much he actually paid for the 4 8-oz jars.
so, he paid
$0.71×32 = $22.72
for the 32 oz of paint, because he bought it in 8-oz jars.
