A) 9s
B) 10s − 0.10(10s)
C) 10s − 0.10s
D) 10s − 1s

Answer 1

the answer is c=10s-0.10s

Answer 2

10s - 0.10s is not equivalent to given situation.

C is correct.

Explanation:

Hailey buys 10 shirts at 10% off

Cost of each short = $s

Total cost for 10 shirts = 10s

Discount Amount = 10% of 10s or 0.10(10s)

Amount to be paid = Amount of 10 shorts - Discount Value

= 10s - 0.10(10s)

= 10s - 1s

= 9s

In calculation steps we can see which are from option.

A, B and D are the steps of calculation.

Therefore, They are equivalent equation except C

Hence, Only C is not equivalent to the situation.
