Answer:
a. 550-8t
b. 454 dollars
Step-by-step explanation:
a. Calling t the number of weeks, the balance in the first account is
while the balance in the second account is
So, the total amount in both accounts is the sum of the balances of the two accounts:
b. To find the total amount in both accounts after 12 weeks, we just need to substitute t=12 into the total balance, and we find:
