Step-by-step explanation:
The price of each caramel macchiato is $5.60
What is the correct function in this case?
The appropriate function is the one that considers the initial amount of $35 , the amount spent for 5 caramel macchiatos, and the balance left which is $7 after the purchase
This means the $35 minus the amount spent equals $7
let us assume that the price per item is x for 5 items, then he spent 5x
35-5x=7
35-7=5x
28=5x
x=28/5
x=$5.60
