If d is the amount of money Andrew deposited each week, which expression represents how much money he have in his account after the tenth week?
-
A - 250+d+4(2d)
B - 250-d+4(2d)
C - 250+6d+4(2d)
D - 250-6d+4(2d)



Answer :

C. 250 + 6d + 4(2d)
250 is the amount of money that Andrew began with. If "d" represents the deposit, and you know that he deposited that same amount of money for the next 6 weeks, you have 6d. Since you also know that you deposited twice the amount of money for the following 4 weeks, then you know that he deposited 2d every week after that, creating 4(2d).
