Answer:
$13.50
Step-by-step explanation:
Both of the items were 40% off, so we can find the sale price of the shirt:
28 - 40% * 28 = 28 - 0.40 * 28 = $16.80
Now subtract this from the total:
24.90 - 16.80 = $8.10
$8.10 is the sales price of the hat. Let's say the price of the hat was h. Then:
h - 40% * h = 8.10
h - 0.40h = 8.10
0.60h = 8.10
h = $13.50
The original price was $13.50.
