y = $0.50x + $4.95

If Kip spent $12.45 at the fair, how many tickets did he buy?

Answer:

x = 15

Explanation:


12.45=4.95+0.5*x×x

Solve the equation


12.45=4.95+0.5x

Rearrange variables to the left side of the equation


-0.5x=4.95-12.45

Calculate the sum or difference


-0.5x=-7.5

Divide both sides of the equation by the coefficient of variable


x=(-7.5)/(-0.5)

Determine the sign for multiplication or division


x=(7.5)/(0.5)

Multiply both the numerator and denominator with the same integer


x=(75)/(5)

Cross out the common factor


x=15

I hope this helps you
