Yes, it is possible if the sweaters on sale are $7.40 each.

Step-by-step explanation:

The sweaters each cost $37. To purchase all four (for herself and 3 sisters) without a sale would be 4 (37) = $148.

40% off the regular price would be 0.40 (148) = $59.20 savings. She would spend 148-59.2 = $88.80.

Is it possible to buy two regular price sweaters and two on sale for $88.80?

2 (37) = $74. If we subtract from the sales total, 88.80-74=14.80. This means the two sweaters on sale must each be $7.40. It is possible to save 40%.
