Answer:
A) it costs $4.8
B) 45%
C) 35% discount
Explanation:
The equation:
12 x 0.6 = 7.2
7.2 represents the profit. To find the cost:
12 - 7.2 = 4.8
The answer is 4.8
17.40 - 12 = 5.4
Now
divide the difference of the prices by the original price:
5.4/12 = 0.45
Turn into percent
45%
Now:
17.40 - 11.31 = 6.09
Same before:
Difference of prices divided by original price
17.40/6.09 = 0.35
35%
