Answer:
A
Step-by-step explanation:
A]
7*5 = 35+15 = 50
10*70 = 70 +14 = 85
15*7 = 105 +15 = 120
20*7 = 140+15 = 155
B]8.50*5 = 42.5
C]10*5 = 50
10*10 = 100
D] = 8*5 = 40 +10 = 50
10*8 = 80+10 = 90
Answer:
<em>(A) $18</em>
<em>(B)
</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: 
He spent total $55.50 on ride tickets and fair admission.
So, the cost of admission to the fair will be: 
(B)
If
represents the number of ride tickets and
represents the total cost, then the cost for
number of ride tickets is 
So, the linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission will be: 
(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>.
