Tomas bought 80 tickets for rides at an amusement park. each ride costs 5 tickets, and tomas has been on x rides so far. which expression is equivalent to the number of tickets that tomas has left? select all that apply. a. 80 – 5x b. 80 + 5x c. 5(16 – x) d. –5x + 80 e. 5(16 + x)

After Tomas bought 80 tickets and had been on 0 rides, the number he had left was 80. Each ride decreases that number by 5 tickets, so x rides will decrease that number by 5x tickets. The number left after x rides is then ...

... 80 - 5x . . . . . matches selection A

The commutative property of addition lets us change the order of these terms to ...

... -5x +80 . . . . . matches selection D

The distributive property lets us factor out 5, so the expression can be written ...

... 5(16 -x) . . . . . matches selection C

___

Any expression where x or 5x is being added cannot be right, as Tomas's remaining tickets do not increase when he rides another ride.

the answer is ! ?
