Answer:
C = 5x + 8y + 15z + 1.5r + 15
Where C = cost for the family of 6
Step-by-step explanation:
Let:
x = number of children under 10
y = number of children 11-16
z = number of all others (16 and above)
r = number of rides
Cost:
Under 10 = $5
11-16 = $8
Above 16 = $15
Ticket Ride = $1.50
We have an additional $15 for parking
So from there, we can find the cost by getting the total:
Cost for each TOTAL
x x $5 $5x
y x $8 $8y
z x $15 $15z
r x $1.50 $1.50r
Constant : $15 for parking
So the expression would then be:
C = 5x + 8y + 15z + 1.5r + 15
Given:
6 family members
x = 3
y = 1
z = 2
r = 5
We fill in the formula
C = 5x + 8y + 15z + 1.5r + 15
C = 5(3) + 8(1) + 15(2) + 1.5(5) + 15
C = 15 + 8 + 30 + 7.5 + 15
C = 75.50
Answer:
n = 121
Step-by-step explanation:
Given,
Amount invested = $250,000
Quarterly payment (P) = $5500
Interest Rate (Quarterly) (r) = 8% /4 = 2%
Account balance = $ 0
Present value of Annuity formula ,
Present value = ![P\times\dfrac{1-(1+r)^{-n}}{r}](https://tex.z-dn.net/?f=P%5Ctimes%5Cdfrac%7B1-%281%2Br%29%5E%7B-n%7D%7D%7Br%7D)
![250000 = 5500\times\dfrac{1-(1+0.02)^{-n}}{0.02}](https://tex.z-dn.net/?f=250000%20%3D%205500%5Ctimes%5Cdfrac%7B1-%281%2B0.02%29%5E%7B-n%7D%7D%7B0.02%7D)
1.02⁻ⁿ = 0.091
-n ln(1.02) = ln (0.091)
n = 121
Hence it will take 121 Quarters to account balance $0.
You have 5 types of pasta and 4 flavors, 5*4=20, and one choice, 1/20 One over twenty, and I think that your answer is nineteen over twenty 19/20. Sorry if I am wrong. Forgive me.
