1. The county fair charges $1.50 per ticket for the rides. Jermaine bought 20 tickets for the rides and spent a total of $48.75

MAVERICK [17]

Answer: Our variable be z for fair admission and our required linear equation will be

$\$1.50x+z=\$48.75$

Explanation:

Since we have given that

Cost per ticket for the rides =$1.50

Total amount she spent = $48.75

Let the total cost be y

Let the number of ride tickets be x

<u>a) Define your variable:</u>

Let the amount spent on fair admission be z

<u>b) Write a linear equation that can be used to determine the cost for ride tickets and fair admission:</u>

Our required equation will be

$\$1.50x+z=\$48.75$

Here, number of ride tickets = 20

So,

$20\times 1.50+z=48.75\\\\30+z=48.75\\\\z=48.75-30=18.75$

So, the cost for fair admission = $18.75
