Using proportions, it is found that their total monthly payment is of $2,887.37.
What is a proportion?
A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the payments are given as follows:
- $2,165.61 for principal and interest.
- 1/12 = 0.0833 of $6,478.50 for taxes.
- 1/12 = 0.0833 of $2,186 for insurance.
Hence:
2165.62 + 0.0833 x 6478.5 + 0.0833 x 2186 = $2,887.37
Their total monthly payment is of $2,887.37.
