1. The county fair charges $1.50 per ticket for the rides. Jermaine bought 20 tickets for the rides and spent a
makvit [3.9K]

Cost per ticket for the rides = $1.50.

a) Let us assume the number of ride tickets = x.

Total cost of x number of rides = y.

Total amount spent = $48.75.

Amount spent on 20 tickets = 20 × 1.50 = $30

<em>Fair admission charge = Total amount spent - Amount spent on 20 tickets</em>

<em> =  $48.75 - $30 = $18.75.</em>

Let us apply slope-intercept form y=mx+b to get the equation.

Total cost of x number of tickets at the rate $1.50 each ticket = 1.50x.

To<em>tal cost of fair = Total cost of x number of tickets + Fair admission charge.</em>

<h3>b) y = 1.50x + 18.75.</h3>
