Question

Ok guys i need your help. can someone give me the answer and EXPLAIN it? I don´t get any of this and if someone explains, it MIGHT help.

Answer 1

Answer: C. y=25x+125

Step-by-step explanation:

it multiplies by 75 and adds 125 each time

Answer 2

C. Y = 75x + 125

Number of credits jumps two from 3 to 5 and the yearly cost jumps from $350 to $500...

$500 - $350 = $150

$150 ÷ by 2 (number of credits) equals $75 (per number of credit)

Thus, we can do:
$75 x 5 = $375

$500 - $375 = $125

I hope that helps...! :>
