Answer:
<h3><u>Option 1</u></h3>
Earn $50 every month.
- Let x = number of months the money is left in the account
- Let y = the amount in the account
- Initial amount = $1,000

This is a <u>linear function</u>.
<h3><u>Option 2</u></h3>
Earn 3% interest each month.
(Assuming the interest earned each month is <u>compounding interest</u>.)
- Let x = number of months the money is left in the account
- Let y = the amount in the account
- Initial amount = $1,000

This is an <u>exponential function</u>.
<h3><u>Table of values</u></h3>
<u />

From the table of values, it appears that <u>Account Option 1</u> is the best choice, as the accumulative growth of this account is higher than the other account option.
However, there will be a point in time when Account Option 2 starts accruing more than Account Option 2 each month. To find this, graph the two functions and find the <u>point of intersection</u>.
From the attached graph, Account Option 1 accrues more until month 32. From month 33, Account Option 2 accrues more in the account.
<h3><u>Conclusion</u></h3>
If the money is going to be invested for less than 33 months then Account Option 1 is the better choice. However, if the money is going to be invested for 33 months or more, then Account Option 2 is the better choice.
Given:Painting priced at $600.
If paid using credit card and in installment basis.$600 x 16% = $96 interest on credit card balance$600 + $96 = $696 total debt$696 ÷ 12 months = $58 monthly payments
If paid using cash from cash advance.$600 x 5% discount = $30$600 - $30 = $570$570 x 32% = $182.40 interest on cash advance$570 + $182.40 = $752.40$752.40 ÷ 12 months = $62.70 monthly payment
It is cheaper for Paul to buy the painting using his credit card. He will only pay $58 per month on his credit card provider compared to the $62.70 monthly bill if he used cash advance.
Hope this helped☺☺
