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>

The owner of a bike shop would like to analyze the sales data to determine if the business is growing, declining, or remaining f
igomit [66]

The sales growth is = $25,000

<h3>The analysis of sales data</h3>

The revenue generated from a business like that of the owner of a bike shop is by multiplying the number of sales and the sales price or average service price.

The sales Revenue for Last Year =$125,000

The Sales Revenue for Current Year = $150, 000

Therefore the sales growth can be gotten by subtracting the current year from the previous year. Which is,

$150, 000 - $125,000 = $25,000
