Answer:
<em>1500(1.02)^x + 600x</em> is how much he has in savings at the end of x years where it be in the bank or elsewhere
Step-by-step explanation:
x is in years
Let's just think about the investment of 1500 in an account earning 2% per year.
Before the years even start, you are at 1500 ( present value).
The next year (year 1), it would be 1500*.02+1500=(1500)(1.02).
The next year (year 2), it would be 1500(1.02)(.02)+1500(1.02)=1500(1.02)(1.02).
We keep multiplying factors of (1.02) each time.
So for year x, you would have saved 1500(1.02)^x.
Now we are saving 50 cash per month. Per year this would be 12(50) since there are 12 months in a year. 12(50)=600.
So the first year you would have 600.
The second year you would have 600(2) or 1200.
The third year you would have 600(3) or 1800.
Let's put this together:
1500(1.02)^x + 600x

Answer:
<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>
Step-by-step explanation:
Let's find out the amount of cards that Math and Seth will have in week 20, using the information shown in the graph and table:
Amount of cards Seth has in week 20 = 20 * 4 = 80
The equation to find out the amount of cards, c, Seth has in week w:
c = 4w
Amount of cards Matt has in week 20 = 20 + (2 * 20) = 20 + 40 = 60
The equation to find out the amount of cards, c, Matt has in week w:
c = 20 + 2w
<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>
