Answer 2

Î chose C. I want to know if I am correct or wrong.

Answer 3

Let's see. Does it make sense?

C. 250 + 6d + 4(2d)

that says: 250 and add 6 times d

that matches
$250 in his savings account
If d is the amount of money Andrew deposits each of the first 6 weeks,

then 4*(2d) means twice that amount each week for another 4 weeks.
2d is twice the amount, and we do that for 4 weeks.

Yes, it looks good.
