To find the constant of proportionality, we need to determine the ratio of the number of bucks to the number of months for each scenario.
For the first scenario, Sophie read 4 bucks in 2 months:
4 bucks / 2 months = 2 bucks/month
For the second scenario, Sophie read 10 bucks in 5 months:
10 bucks / 5 months = 2 bucks/month
From both scenarios, we can see that the constant of proportionality is 2 bucks/month.
Sophie read a total of four bucks in two months. Then she read 10 bucks in five months. What is the constant of the PROPORTIONALITY?
