Answer:

x = $450

Step-by-step explanation:

Total cost of the surfboard = $570

Total amount saved from babysitting = $120

Amount remaining = $x

Total cost of the surfboard = Total amount saved from babysitting + Amount remaining

$570 = $120 + $x

Subtract 120 from both sides

570 = 120 + x

570 - 120 = 120 + x - 120

450 = x

x = $450

Check:

570 = 120 + x

570 = 120 + 450

570 = 570
