Question

Fuel x cost $2 per gallon and fuel y cost $3 per gallon. You have at most $18 to spend on fuel. Write a system of linera inequalities to represent this situatiom

Answer 1

2x + 3y <= 18, x >= 0, and y >= 0

Explanation:

Answer 2

`2x + 3y \leq 18`

Explanation:

Given :

fuel x is $2 i.e $2x

fuel y is $3 i.e $2y

As mention in the question the cost will be almost $18 to spending the fuel

So

Linear equation can be written as

`2x + 3y \leq 18\\\ where\ x\geq 0\ and\ y\geq 0`
