1. the county fair charges $1.25 per ticket for the rides. jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. jermaine spent his money only on ride tickets and fair admission. the price of the fair admission is the same for everyone. use y to represent the total cost and x to represent the number of ride tickets. (a) write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission. (b) define your variables.

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

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
