san4es73 [151]

Answer:

<em>(A)  $18</em>

<em>(B)   y=2.50x+18</em>

<em>(C)   Coefficient of x-term represents the cost for each ride ticket and constant term represents the cost of admission to the fair.</em>

Step-by-step explanation:

(A)

The county fair charges $2.50 per ticket for the rides and Henry bought 15 tickets for the rides.

So, the total cost of the 15 tickets will be:  (\$2.50*15)= \$37.50

He spent total $55.50 on ride tickets and fair admission.

So, the cost of admission to the fair will be:  (\$55.50-\$37.50)= \$18

(B)

If x represents the number of ride tickets and y represents the total cost, then the cost for x number of ride tickets is \$2.50x

So, the linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission will be:   y= 2.50x+18

(C)

In the above linear equation, <u>coefficient of x-term is 2.50, which represents the cost for each ride ticket</u>.

And the <u>constant term is 18, which represents the cost of admission to the fair</u>.
