Answer:it is false.
Explanation:
Let us assume that the regular price of the shirt is $x.
The shirt is on sale for 40% off the regular price. The amount that is taken off the shirt would be
40/100 × x = 0.4 × x = 0.4x
The new price of the shirt would be x - 0.4x = $0.6x
you have an additional 20% off coupon. The value of the coupon would be
20/100 × 0.6x = 0.2 × 0.6x = 0.12x
The cost of the shirt if the coupon is applied would be
0.6x - 0.12x = 0.48x
If you assumed that the shirt will ultimately be 60% off the original price, the cost of the shirt would be
x - 60/100 × x = x - 0.6x = 0.4x
Therefore, they are not equal and si, it is false.
