Question 933815: A company manufactures both mountain bikes and trail bikes. The cost of materials for a mountain bike is $80, and the cost of materials for a trail bike is $40. The cost of labor to manufacture a mountain bike is $70, and the cost of labor to manufacture a trail bike is $40. During a week in which the company has budgeted $3,000 for materials and $2,750 for labor, how many mountain bikes does the company plan to manufacture?

You can put this solution on YOUR website! x, quantity of mountain bikes
y, quantity of trail bikes
Account for materials: 80x+40y=3000
Account for labor: 70x+40y=2750
Those are two linear equations in two unknown variables.
Solve the system.
