Question

It costs $20 plus $1.50 per hour to rent a golf cart.

Answer 1

$20 base fee + ($1.50 per hour × X hours rented) = Y the overall price

20+(1.50×X)=Y

Example:
Let's say the golf cart is rented for 3 hours.
X = 3

$20 base fee + ($1.50 per hour × 3 hours)
20+(1.50×3)
20+4.50= $24.50

So in this example Y=$24.50
