Answer:
i think it on of these C. y = 2x2 - 6x + 80
D. y = 2x2 + 6x - 80
Step-by-step explanation:
Let's write equations for both Monica and Michael to represent what they should have.
Let's have W represent the number of weeks that pass.
So Monica already has $25 and wants to save $5 each week, her equation will be:
Monica = 25 + 5W
Michael has $16 and will save $8 each week, so his equation is:
Michael = 16 + 8W
We want to know the number of weeks where Monica and Michael have the same amount of money, so:
Monica = Michael or 25 + 5W = 16 + 8W
Solve for W:
1. subtract 16 from both sides to get 9 + 5W = 8W
2. subtract 5W from both sides to get 9 = 3W
3. divide both sides by 3 to get W = 3
So it takes 3 weeks for them to have saved the same amount of money. Plug W = 3 back into one of the equations (it doesn't matter which one) to figure out how much they saved.
16 + 8W = 16 + 8*(3) = $40
Follow the formula Interest=(Principal)(Rate)(Time)
So, the equation would be:
I= 10,000x0.09x5
This equals $4,500
So, the amount of interest is $4,500
