Answer:
The correct answer is $9,57.
Explanation:
To be able to solve this exercise we must begin by analyzing the information we have:
We know that the cost of 5 cans of dog food is 4.35.
Now we are asked to find out how much 11 cans of dog food would cost.
Having 3 of 4 unknowns resolved, the most convenient thing would be to do a cross-multiplication:
if 5 cans ----- 4.35
11 cans ---- x
5.x = 4,35 . 11
5x = 47,85
x = 47,85 : 5
x = 9,57
In this way we can verify that the correct answer is 9.57.
