Question

Sarah received 55 for her birthday. She used some of that money to buy 3 shirts priced at m dollars each. How much money does Sarah have left? Write your answer as an expression.

Answer 1

Step-by-step explanation:

Sarah received 55 for her birthday.

Therefore, the total money she had = 55

Since she used some of that money to buy 3 shirts priced at m dollars each.

Then the total amount she spent = 3 times m= 3m

Now, the amount of money she had left = 55-3m

Hence the required expression is 55 - 3m
