Question

Hannah received $30 for her birthday and bought 3 shirts that were all the same price. If she had $9 left over, which equation shows how to determine how much each shirt cost?

Question 6 options:

3x = 39


3x = 30


x + 9 = 30


3x + 9 = 30

Answer 1

d.3x+9=30 because x is the price of the three shirts which you times how many you bought and the price of one and add nine

Answer 2

money spent + money left over = total money

money spent + 9 = 30

We don't know the price of each shirt, so let x = price of 1 shirt.
Then, 3 shirts cost 3 times as much as x, or 3x.
She spent 3x.

3x + 9 = 30
