Karah can wash 2 cars every 19 minutes. The relationship is represented by the equation y=9.5x where x is the number of cars and y is the number of minutes. Identify the constant of proportionality. How long will it take Karah to wash 17 cars?
The constant of proportionality is _. It will take Karah _ minutes to wash 17 cars
The constant of proportionality can be found by looking at the coefficient of x in the equation. In this case, the coefficient of x is 9.5. Therefore, the constant of proportionality is 9.5.
To find out how long it will take Karah to wash 17 cars, we need to substitute x = 17 into the equation y = 9.5x.
y = 9.5 * 17
y = 161.5
Therefore, it will take Karah 161.5 minutes to wash 17 cars.
