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.
Deposit = $75 = 30%
(30/100)x = 75
(3/10)x = 75
0.3x = 75
x = 75/0.3
x = 250
Total cost = $250
deposit = $ 75
Total - deposit = $175
Thus, Marc owe $175 for the rug.
5 ounces for 4 weeks is 20 ounces.
There are 16 ounces in a pound so 20 ounces is 1 pound and 4 ounces.
8 lbs 3 oz plus 1 lb 4 oz is 9 lbs 7 oz.
After 4 weeks, he should weigh 9 lbs 7 oz
Here we're dividing a fraction (5/8) by another fraction. We could obtain the same result by inverting the divisor (2/5) and then multiplying (5/8) by (5/2).
The product is 25/16.
Thus, 2/5 divides into 5/8 25/16 times, or 1 9/16 times.
