Answer:
$(55-3m) is the amount of money she has left
Step-by-step explanation:
In this question, we are asked to give an expression to represent how much money was left after Sarah had bought some certain stuffs at some prices using the money she received at her birthday.
Firstly, we identify that the total amount of money she has to spend is $55.
Now let’s project her total spendings. She bought 3 shirts with each shirt costing $m.
The total amount spent on the shirts is thus; 3 * $m = $3m
The amount of money she has left is the difference.
Mathematically, this is equal to $55 - $3m
Answer:
the required expression is 55-3m
Step-by-step explanation:
Sarah received $55 dollar sign,for her birthday.
Therefore, Sarah had the total money of $55
she used some of that money to buy 3 shirts priced at m dollars each.
Then the total amount she spent =3 multiply by m
which equals to 3m
Now, the amount of money she had left
The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:
= 55-3m (in dollars)
Remaining Money = 55 - 3m
Hence, the required expression is 55-3m
