Question

:)

Mariam sells tires for $90 each and a service plan for $50. One customer

pays $410 for some tires and the service plan. Which equation represents

how many tires, t, the customer purchased?

A 410 = 50 + 90t

B 410 = 90 + 50t

© 410 = 50t + 90

D 410 = 90(4t) + 50

Answer 1

the answer is A

Explanation:

410 is the total amount paid

so 50 dollars was a base fee for the service charge

and 90 was per tire. Because we dont know how many tires she bought 90 x number of tires(t) = 90t

so 410 dollars = 50 dollars(service fee) + 90 dollars ( multilied by number of tires "t")
