Determine if there is a proportional relationship. If so, write in y=kx form.
A cola company makes $2.66 profit for every 7 cans they sell. They also profit $7.60 every 20 cans sold
To determine if there is a proportional relationship, we need to compare the ratios of profit to the number of cans sold for both scenarios.
For the first scenario, the ratio of profit to the number of cans sold is 2.66/7 = 0.38.
For the second scenario, the ratio of profit to the number of cans sold is 7.60/20 = 0.38.
Since both ratios are equal, we can conclude that there is a proportional relationship. The equation in y=kx form can be written as:
y = 0.38x
