I am trying to work this problem and need help. Mary bought 2 pairs of identical jeans at a sale. She paid regular price for the first pair and paid half price for the second pair. If the total cost was $45.00,what was the regular price of the jeans? 2x  1/2x =45.

2x  1/2x =45
1.5x = 45
x = 45/1.5
x = 30
