Question

If Adam buys 5 snakes at 20% off and each snake costs s dollars, which expression is NOT equivalent to the situation stated?A)4sB)5s − 0.20(5s)C)5s − 0.20sD)5s − 1s

Answer 1

5s − 0.20s

5s − 0.20s = 4.8s

The other three expressions are equivalent to 4s.

Answer 2

C) 5s - 0.2s is not equivalent.  This would be paying for 5 snakes and subtracting 20% of the price of one snake, not 20% of the price of all 5 snakes.
