Carlos has $45 in his lunch account. He spends $2.25 each day on lunch, d. Elijah has $50 in his lunch account. He spends $2.50 each day on lunch, d. The two boys used all the money in their lunch account on the same day. Which equation could be used to determine the number of lunches each boy was able to purchase with the amount of money they had in their account? A. 45 − 2.25d = 50 − 2.5d
A. , 45 − 2.25d = 50 − 2.5d

B. 45 + 50 = 2.25d + 2.5d
B. , 45 + 50 = 2.25d + 2.5d

C. 45 + 2.25d = 50 + 2.5d
C. , 45 + 2.25d = 50 + 2.5d

D. 45d − 2.25 = 50d − 2.5
D. , 45d − 2.25 = 50d − 2.5
