Some students want to start a business that cleans and polishes cars. It takes 2.5 hours of labor and costs $1.5 in supplies to clean a car. It takes 1.5 hours of labor and costs $3 in supplies to polish a car. The students can work a total of 150 hours in one week. They also decide that they want to spend no more than $120 per week on supplies. The students expect to make a profit of $6.75 for each car that they clean and a profit of $9.50 for each car that they polish. Hours’ constraint is: * 2.5X1+1.5X2≤150 2.5X1+1.5X2≤120 2X1+1.5X2≤120 1.5X1+2.5X2≤15
