Afan pays $875 for 3 premium seat tickets. Another fan pays $2125 for 8 premium seat tickets. Write a linear model for the cost
grandymaker [24]

The equation is : C=250t +125 where C is the cost and t represent the number of tickets purchased.

Step-by-step explanation:

Let the cost of premium seat ticket be C

Let the number of tickets a fan buys to be t

Then, presenting the information as ordered pairs of coordinates (x,y) will be;

Fan 1, (3,875)

Fan 2, (8,2125)

Plot the ordered pairs as coordinates on a graph tool, find the slope of the linear graph and equation in slope intercept form as;

m=Δy/Δx

m=2125-875/8-3

m=1250/5

m=250

Equation of the graph,

Δy/Δx=250

y-875/x-3 =250

y-875=250(x-3)

y-875=250x-750

y=250x-750+875

y=250x+125

C=250t +125 where C is the cost and t represent the number of tickets purchased

If its 2 dollar per book and they need 300 dollar, you need to divide 300 by 2 which is 150 students. you will need 150 students for each to pay 2 dollars. just to be sure, 150 students times 2 dollar is 300 dollars

Answer:

x = 6

Step-by-step explanation:

The sum of the angles of a triangle is 180

70+60+8x+2 = 180

Combine like terms

132 +8x = 180

Subtract 132 from each side

132+8x-132= 180-132

8x = 48

Divide each side by 8

8x/8 = 48/8

x = 6
