Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
8x + 3y = 20
x + 4y = 17
(1, 4)
<u>Step 2: Check</u>
<em>Plug and verify the coordinates is a solution.</em>
- Substitute in point [1st Equation]: 8(1) + 3(4) = 20
- Multiply: 8 + 12 = 20
- Add: 20 = 20

- Substitute in point [2nd Equation]: 1 + 4(4) = 17
- Multiply: 1 + 16 = 17
- Add: 17 = 17

∴ Since both equations work out, (1, 4) is a solution to the systems of equations.
A system of linear equations that must be solved algebraically is when numbers are very large or very small or when those that have to be accurate to several decimal places which is hard to graph.
Given is :
The annual income of Richard = $34200
Hence, his monthly income becomes =
= $2850
So, the maximum amount that he can spend per month paying off credit cards and loans and not be in danger of credit overload can be a maximum of 20% of this income.
So, 20% of 2850 is = $570
Hence, approximately $570 can be spent a month.
As, the question has no options to choose from, but the question is complete in itself, so this is the best possible answer.
