Answer:
A Used Truck Would Go For Around $18,000
Step-by-step explanation:
A used truck would go for around $18,000.
The reason a used truck would go for around $18,000 dollars is because if a new truck costed $45,000, and a used truck usually goes for around 40% of that, all you have to do is multiply 45,000 by .40 to get 40% of 45,000.
So, in conclusion, a used truck would cost about $18,000 because 40% of $45,000 is $18,000.
Once ur lines are graphed, the solution is where the lines intersect. So by graphing however many equations u have, the point where they intersect is the solution....unless of course u have parallel lines, then there is no solution. And if ur lines are coincident, the same line on top of each other, then there is infinite solutions.
As a fraction it would be 8/5
