Assign variables to you unknowns.
c = $ cars
t = $ trucks
6c + 3t = 4800
8c + t = 4600
use substitution or elimination to solve the system of equations.
using elimination.. multiply second equation by -3 and add to the other to combine equations into one.
6c + 3t = 4800
-3(8c + t = 4600)
---------------------------
-18c + 0 = -9000
c = 9000/18
c = 500 $
use this in one of the equations to find the cost of a truck.
8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600 $
question asks
2(500) + 3(600) =
1000 + 1800 = 2800 $
The answer is B because the x describes the domain and it can also be the input value
Inga needs 3 more years to pay off the whole amount.
<h3>What is the monthly payment?</h3>
A portion of the monthly payment is called the principal, which is the original amount borrowed.
First year balance = $19,691.28
Monthly payment = $273.49
Annual payment = 273.49×12 = $3281.88
Remaining balance after 1 year = 19,691.28 - 3281.88 = $16,409,4
After 3 years balance = $9845.64
- Remaining balance after payment (4 years) = 9845.64-3281.88 = $6563.76
- Remaining balance after payment (5 years) = 6563.76-3281.99 = 3281.88
- Remaining balance after payment (6 years) =3281.88-3281.88 = 0
Hence, Inga needs 3 more years to pay off the whole amount.
