Answer: C. 35m + 50 = 410

Explanation:

We know the cost is 410, so it will be = 410

We know that she pays 35 each month, which mean it is 35m

She put down 50 at the beginning, so it is + 50

So our equation is

35m + 50 = 410

Answer:

C

Explanation:

I'm guessing you misspelled 410 as 419, but the equation is y=mx+b

Kim wants the money amount she puts in to pay off her $410 phone, or in other words, add up to $410.

The constant, or b, is 50. The m is 35, and the x is the months.

35m + 50 = 410
