Answer:
The amount of change she received was [tex](10-0.03y)[/tex] dollar.
Step-by-step explanation:
Price of each carton of milk is [tex]y[/tex] cents and she bought 3 cartons of milk.
We know that, 1 dollar = 100 cents
So, 1 cent = [tex]\frac{1}{100}=0.01[/tex] dollar.
and [tex]y[/tex] cents [tex]=0.01y[/tex] dollar.
Thus, the total price of 3 cartons of milk [tex]=(0.01y*3)=0.03y[/tex] dollar.
She gave the cashier $10.
So, the amount of change she received [tex]=(10-0.03y)[/tex] dollar.
