1. the county fair charges $2.50 per ticket for the rides. henry bought 15 tickets for the rides and spent a total of $55.50 at the fair. henry spent his money only on ride tickets and fair admission. the price of the fair admission is the same for everyone. use x to represent the number of ride tickets and y to represent the total cost. (a) find the cost of admission to the fair. explain how you found the cost of admission. (b) write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission. (c) explain what the coefficient of x and the constant of your linear equation represents. 

Answer and explanation

a is $18.00 because Z is a constant

b is y=2.50x+18.00

c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute

that leads to 55.50 =2.50(15)+z

and the untimely z = 18.00 dollars .  

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
