Johanna took $125 to the mall. She bought 5 shirts (s) that cost the same price. Which expression represents the amount of money
svp [43]

Answer:

I think its something like: Money Leftover = 125 - (price of one shirt * 5)

Step-by-step explanation:

just use variables in the place of "price of one shirt" and "Money Leftover".

multiplying the price of one shirt by five since she buys 5 of the same shirt and subtracting that value from her budget will leave you with the amount of money she had left after the purchase.
