a. $ (675-18t)

b. $477

Step-by-step explanation:

a. We are to write an expression that shows the total amount in both accounts.

Mathematically that would be; amount in the expense account + amount in the fund raising account

That would be; 500-60t + 175 + 42t = 500+175-60t + 42t = 675 - 18t

The total amount in both accounts is $ (675 - 18) after t weeks

B. after 11 weeks, what we do is to just substitute the value of 11 for t in the added equation above

Thus;

675 - 18t = 675-11 (18) = 675 - 198 = $477
