While she was travelling, Zainab took advantage of the convenience of cash withdrawals on her credit card since her Canadian debit card wasn't accepted in the country she was in. According to her travel budget she withdrew \$125 every day for food, activities and shopping for 21 days. When she got home, on the 21st day, she checked her credit card bill on-line and it showed that she had been charged interest already even though her payment wasn't past due. It turns out that interest is compounded daily on cash withdrawals, from the day the cash is withdrawn. If the interest rate on cash withdrawals is 28%, what was her total bill when she got home? What would be the total interest paid? QUESTION 8 Aya and Sakura would like to buy a house and their dream home costs $500,000. Their goal is then to save $50,000 for a down payment and then would take out a mortgage loan for the rest. They plan to put their monthly saved amount in a conservative mutual fund that has a track record of a 4.25% rate of return. To be sure they don't go spending this money on other things, they are going to move it into their investment account at the beginning of each month. Their hope is to be able to buy this home in 7 years. What would their monthly savings amount have to be to reach this goal? What will be the total interest earned? QUESTION 9 Aya and Sakura have now saved up their down payment to buy a home, but they still need to borrow to cover the rest. For the home they want this will require a mortgage of $450,000 to cover the remaining amount and they're not sure whether they could afford the monthly loan payments. The bank has offered them a mortgage interest rate of 4.25%, compounded monthly. How much would they have to be able to afford to pay each month in order to pay off their mortgage in 25 years? What is the total amount that would be paid to the lender after 25 years of payments
