Answer: C = 28x + 15y
Step-by-step explanation:
To get the total cost, you'll have the add them up. The "x" was right before "$28" which makes it: (28x) and the "y" was right before "$15." which makes it (15x). Now, you'll have to add them up :)
28x + 15y
If they are specifically asking for an answer, then your official answer will be
28x + 15y = 43 (I'm not sure whether it would be an "x", or a "y", or anything something like that, lol)
or
43
but if not then you're final answer would be-
28x + 15y
hope it helped xx
