(8.4) Recall that your client intends to save for a downpayment on a house so they can buy their first home in 9 years. Recall that they have an initial saving of $1,600 and will save $125 per month for their downpayment. They think the kind of house they want will cost around $420,000. After they use all of the money they have saved for the downpayment, how much will they have to borrow? (Hint: You already calculated the total they should have saved in a previous question. Also, their home downpayment money does NOT earn any interest so there is no compounding to apply here. This is linear growth.)
