Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Maura is a salon owner. Yesterday, she did 3 haircuts and colored the hair of 5 clients, charging a total of $568. Today, she did 3 haircuts and colored the hair of 2 clients, charging a total of $292. How much does Maura charge for her services?Maura charges $____ for a haircut and $____ for a coloring.
Define variables: Let's define two variables: let x be the cost of a haircut and y be the cost of coloring. We can write two equations based on the information given:For yesterday: 3x+5y=568For today: 3x+2y=292
Use elimination method: To use elimination, we want to eliminate one of the variables. We can do this by multiplying the second equation by −1 so that when we add the two equations, the x terms will cancel out.Multiplying the second equation by −1 gives us: −3x−2y=−292
Add equations: Now we add the two equations together:(3x+5y)+(−3x−2y)=568+(−292)This simplifies to:3y=276
Solve for y: Next, we solve for y by dividing both sides of the equation by 3:33y=3276y=92So, Maura charges $92 for coloring.
Substitute y: Now that we know the cost of coloring, we can substitute y=92 into one of the original equations to find x. We'll use the equation for today:3x+2(92)=2923x+184=292
Solve for x: Subtract 184 from both sides to solve for x:3x=292−1843x=108
Final result: Finally, divide both sides by 3 to find the cost of a haircut:x=3108x=36So, Maura charges $36 for a haircut.
