Answer:
C, 1.35
Explanation:
Let's add the prices of the items together first since they got 15% off when they bought it together.
1 + 3.50 + 3.50 + 1 = 9
Next, we will do 15% off of 9.
15% x 9 =
(15:100) x 9 =
(15 x 9):100 =
135:100 = 1.35
$1.15
add the cost of all of the items: 1 + 3.50 + 3.50 + 1 = 9
multiply 9 by the given discount: 9 x 0.15 = 1.35
you get 1.15, this is the dollar price of the discount
