At the bakery shop, each baker works at his or her own speed, making the same number of cakes each day. Marissa makes 28 cakes in 2 weeks, Carlos makes 60 cakes in 20 days, and Shelby makes 5 cakes in 2 days. When the shop owner graphs the relationship between the number of cakes made and days, who has the steepest graph? Explain.

1 answer

Just find the unit rate for each person.

Marissa's rate = 28 cakes/ 2 weeks = 28/14 cakes per day = 2 cakes/day
Carlos' rate = 60 cakes/20 days = 3 cakes/day
Shelby's rare = 5 cakes/2 days = 2/5 cakes/day

How do you think this relates to the steepness of the graphs ?
