Answer:
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.
