(1 point)

Student A: It will cost $160 because
$20 x 8 = $160

Student B: It will cost $720 because
$70 + $20 = $90
8 months x $90 = $720

Student C: It will cost $580 because
70(8) + 20
560 + 20
= 580

Student D: It will cost $230 because
20(8) + 70
160+ 70
= 230

Answer 1

Equation: y = 20x + 70 (x = number of months, y = total cost).

For 8 months: y = 20(8) + 70 = 160 + 70 = $230.

Correct student/work: Student D.
