Dasher spent $120, Prancer spent $240, and Cupid spent $360
Step-by-step explanation:
Divide 720 by 2 and you get 360, which was cupids total. There is 360 left. Subtract 360 by 240 because Dasher spent half as much as prancer did. You get 120, which is Dasher's total. The 240 you subtracted is Prancer's total.
