Answer:
Explanation:
Given:
Discount = original price × discount fraction
Discounted price = original price - discount
Discount fraction = 20%
= 20/100
A.
Original price of shirt = $x
Original price of hat = $(x + 10)
Discounted price of shirt = $x - $0.2x
= $0.8x
Discounted price of hat = $(x + 10)
- 0.2$(x + 10)
= $0.8 × (x + 10)
Difference of discounted price of hat to shirt = 0.8(x + 10) - 0.8x
= $8
B.
Original price of shirt = $x
Original price of hat = $ 1.5 × x
Discounted price of shirt = $x - $0.2x
= $0.8x
Discounted price of hat = $ 1.5 × x
- 0.2 × $ 1.5 × x
= $ 1.2x
Difference of discounted price of hat to shirt = 1.2x - 0.8x
= $ 0.4x
