A fair costs $28 for admission plus $3 for each roller coaster ride.
Given that x represents the number of roller coaster rides, choose the algebraic expression that models this situation.
A
B
D
E
28x + 3
31x
31
28 + 3x

Answer 1

You answer is: 28 + 3
`x`

Since $28 is a one-time fee and does not have to be paid again for each and every ride, it does not need a variable in front of.

But for every ride you want, you pay $3 so you need the variable "
`x`" which represents how many times you ride.

For example, if you ride the roller coaster once, your total amount, in dollars, will be:

T = 28 + 3 * (1)

T = $31

But if you ride the roller coaster 3 times, your cost, in dollars, will be:

T = 28 + 3 * (3)

T = 28 + 9

T = $37
