After lunch, Hailey goes to the pet store. Suppose Hailey buys 5 Guinea pig, which expression will not give Hailey total cost
If we assume that each Guinea pig costs the same amount, we can represent the total cost as the product of the number of Guinea pigs (5) and the cost per Guinea pig (let's say "x").
Therefore, the expression that will not give Hailey the total cost is: 5 + x.
This is because adding 5 to the cost per Guinea pig does not represent multiplying the number of Guinea pigs (5) by the cost per Guinea pig (x).
