How long does it take for Valentina to perform each type of service, assuming the amount of time doesn't vary from client to client?It takes Valentina _ minutes to give a haircut and _ minutes to color a client's hair.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Valentina is a hairdresser. Before her lunch break, she gave 4 haircuts and colored the hair of 1 client in 197 minutes. After lunch, she gave 2 haircuts and colored the hair of 2 clients in 226 minutes. How long does it take for Valentina to perform each type of service, assuming the amount of time doesn't vary from client to client?It takes Valentina _ minutes to give a haircut and _ minutes to color a client's hair.
Define Variables: Let's define two variables: let h be the time it takes Valentina to give a haircut, and c be the time it takes to color a client's hair. We can then write two equations based on the information given.
Write Equations: For the morning session, the equation is 4h+1c=197 minutes.For the afternoon session, the equation is 2h+2c=226 minutes.Now we have a system of equations:1) 4h+c=1972) 2h+2c=226
Use Elimination: To use elimination, we need to make the coefficients of one of the variables the same in both equations. Let's multiply the first equation by 2 to match the coefficients of c in the second equation.2×(4h+c)=2×197This gives us:8h+2c=394
Substitute and Solve: Now we have a new system of equations:1) 8h+2c=3942) 2h+2c=226We can subtract the second equation from the first to eliminate c.(8h+2c)−(2h+2c)=394−226
Find h: Simplifying the subtraction, we get:6h=168Now, to find h, we divide both sides by 6:h=6168h=28So, it takes Valentina 28 minutes to give a haircut.
Substitute for c: Now that we know h, we can substitute it back into one of the original equations to find c. Let's use the first equation:4h+c=1974(28)+c=197112+c=197
Substitute for c: Now that we know h, we can substitute it back into one of the original equations to find c. Let's use the first equation:4h+c=1974(28)+c=197112+c=197Subtracting 112 from both sides to solve for c, we get:c=197−112c=85So, it takes Valentina 85 minutes to color a client's hair.
