Question

Huang buys 3 shirts that each cost the same amount, a pair of pants that cost $12, and he pays with a $100 bill. Which expression represents the amount of change Huang should receive? Select three options.

100 – (12(3x))
100 – (3x+12)
(100 – 12) – 3x
(100 – 12)(x+x+x)
100 – (x+x+x) – 12\

Answer 1

Step-by-step explanation: (100 – 12) – 3x

Answer 2

(100 – 12) – 3x

Explanation:

(100 – 12) – 3x would be the correct answer because:

100 is the total amount he paid

12 is the cost of pants

because we don't know the price of shirts yet so it would be called x

He buy in total of 3 shirts so the equation for the price would be 3 * x = 3x

So it would be:

total money paid - pants costs - shirts cost

= 100 - 12 - 3x or (100 - 12) -3x

Hope this helped :)
