The expression that represents the amount of change Huang should receive are: 100 – (3x + 12) and (100 - 12) - 3x and 100 - (x+x+x) - 12
How to solve Algebra Word problem?
100 – (3x + 12)
(100 - 12x) - 3x
100 - (x+x+x) - 12
would be the correct answers 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 - (3x + 12) or (100 - 12) -3x
Complete question is:
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
