Step-by-step explanation:
Principal loan amount is the total amount minus down-payment:

Knowing that
, the monthly payments can be calculated using the formula:
![M=P[\frac{r(1+r)^n}{(1+r)^n-1}]\\\\=23000\frac{(0.006658(1.006658)^{72}}{1.006658^{72}-1}\\\\=403.15](https://tex.z-dn.net/?f=M%3DP%5B%5Cfrac%7Br%281%2Br%29%5En%7D%7B%281%2Br%29%5En-1%7D%5D%5C%5C%5C%5C%3D23000%5Cfrac%7B%280.006658%281.006658%29%5E%7B72%7D%7D%7B1.006658%5E%7B72%7D-1%7D%5C%5C%5C%5C%3D403.15)
Hence, the monthly payment is $403.15
I think is should be (5,0)
Answer:
Children: $13
Adults: $18
Step-by-step explanation:
Well for both sets we can set up the following system of equations,

So first we need to solve for a in the first equation.
3a + 4c = 106
-4c to both sides
3a = -4c + 106
Divide 3 by both sides
<u>a = -4/3c + 35 1/3</u>
Now we plug in that a for a in 2a + 3c = 75.
2(-4/3c + 35 1/3) + 3c = 75
-8/3c + 70 2/3 + 3c = 75
Combine like terms
1/3c + 70 2/3 = 75
-70 2/3 to both sides
1/3c = 4 1/3
Divide 1/3 to both sides
c = 13
Now we can plug in 13 for c in 3a + 4c = 106,
3a + 4(13) = 106
3a + 52 = 106
-52 to both sides
3a = 54
Divide 3 by both sides.
a = 18
<em>Thus,</em>
<em>an adult ticket is $18 and a children's ticket is $13.</em>
