The correct answer is D) 5g - 1g.
This expression does not give the total cost because subtracting 1g from 5g only leaves 4g, which does not account for the original price of the guinea pigs. The expression is missing the discount percentage and does not calculate the final cost accurately.
The other expressions (A, B, and C) all include the original price (g), the discount percentage (0.2), and the number of guinea pigs (5), which are necessary to calculate the total cost.
After lunch, Hailey goes to the pet store. Suppose Hailey buys 5 guinea pigs at 20% off the original price of g dollars per guinea pig, which expression will NOT give Hailey's total cost?
