Answer:the price of one large gift is $60
Step-by-step explanation:
Let x represent the cost of one large gift.
Melanie bought 4 large gifts and 2 small gifts. Since each small gift costs $10, it means that the total amount that Melanie spent is
4x + 2×10 = 4x + 20
Mary bought 1 large gift and 20 small gifts. It means that the total amount that Mary spent is
x + 20×10 = x + 200
They both spent the same amount of money. This means that
4x + 20 = x + 200
4x - x = 200 - 20
3x = 180
x = 60
