Answer:
Step-by-step explanation:
Sophie saved a total of $125 from Christmas and birthday gifts. She wants to purchase some shirts by using her savings.
Each shirt cost $20.00
Let x represent the number of shirts that she bought. The cost of x shirts will be 20 × x = $20x
The amount she has left will be her total savings - the amount spent in buying 20 shirts. This will be expressed as
Let y represent the amount that she has left. The expression becomes
y = 125 - 20x
