Answer:
$0.32
Explanation:
First, we need to see how much the combined cost of the 2 items.
So you add the two costs:
1.29+0.39= 1.68
So the 2 items together cost 1.68
But Eric paid 2 dollars, so he should get some change. But how much?
Since he paid 2 dollars, and the items cost 1.68, we can subtract them to get the change he gets back.
$2-$1.68=$0.32
Eric gets 32 cents back
