The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷( r/k)]
Pv present value?
PMT monthly payment 425
R interest rate 0.055
K compounded monthly 12
T time 1 year
Pv=425×((1−(1+0.055÷12)^(
−12))÷(0.055÷12))
=4,951.26
Answer:
Adult ticket: $7
Child ticket: $2
Step-by-step explanation:
Set up a system of equations where a represents the cost of one adult ticket and c is the cost of one child ticket:
2a + 3c = 20
a + 4c = 15
Solve by elimination by multiplying the bottom equation by -2:
2a + 3c = 20
-2a -8c = -30
Add them together:
-5c = -10
c = 2
Now, we can plug in 2 as c to find the value of a:
2a + 3c = 20
2a + 3(2) = 20
2a + 6 = 20
2a = 14
a = 7
