4x² - x + 1

summing gives :

3x² + 4x - 2 + x² - 5x + 3 ( collect like terms )

(3x² + x² ) + (4x - 5x ) + ( - 2 + 3 )

= 4x² - x + 1

Answer:

A)

x=  the number of ride tickets

y=  the total cost of admission plus how many ride tickets a person purchases

B)

y= 1.25x + 9.5

C)

It is a$1.25 per ticket for the rides at the fair, so it would be 1.25 multiplied by the amount of tickets that are purchased (x). Spencer bought 17 tickets, so 17x1.25= 21.25 and it says that he spent a total of $30.75 at the fair, so 30.75-21.25=9.5, so that means the cost of admission is $9.50.

Step-by-step explanation:

I hope this helps!
