Esther the clown does a face painting at the city carnival, she paints 7 faces every 21 minutes and spends the same amount of time painting each face. Write an equation that relates f, the number of faces she paints, and m, the time she spends painting in minutes.
Q. Esther the clown does a face painting at the city carnival, she paints 7 faces every 21 minutes and spends the same amount of time painting each face. Write an equation that relates f, the number of faces she paints, and m, the time she spends painting in minutes.
Calculate Rate: Determine the rate at which Esther paints faces.Since Esther paints 7 faces every 21 minutes, we can calculate the rate by dividing the number of faces by the time in minutes.Rate = Number of faces / Time in minutesRate = 7 faces / 21 minutes
Simplify Rate: Simplify the rate to find the number of faces painted per minute.To simplify the rate, we divide both the numerator and the denominator by their greatest common divisor, which is 7.Rate = (7 faces/7)/(21 minutes/7)Rate = 1 face/3 minutes
Write Equation: Write the equation that relates f, the number of faces painted, to m, the time spent painting.Since the rate is 1 face per 3 minutes, we can write the equation as:f=31⋅mThis equation shows that for every 3 minutes, Esther paints 1 face.
