All of the items in a bicycle shop are on sale for 30% off the regular price. Rene spends $74.90 to buy a bicycle and a helmet (without taxes). If the regular price of the bicycle is $85, which equation can be used to find the regular price of the helmet, h?
0.3 (74.90 + h) = 85
0.3 (85 + h) = 74.90
0.7 (74.90 + h) = 85
0.7 (85 + h) = 74.90
