Answer:
a). Linear equation; y=1.25 x+12.5
b). The variable are x and y, where;
y is the total cost at the county fair
x is the number of tickets per ride
Step-by-step explanation:
Step 1: Define variable in the linear equation
y=mx+c
where;
y=The total cost at the county fair
x=the number of tickets per ride
m=Cost per ticket ride
c= fair admission price
Step 2: Derive linear equation
In or case;
y=$43.75
m=$1.25 per ticket ride
x=25 tickets
c=unknown
replacing;
43.75=(1.25×25)+c
c=43.75-31.25
c=12.5
The fair admission price=c=12.5
Replacing in the Linear equation;
y=1.25 x+12.5
