Question

Each day, Jake donates money to the global hunger initiative according to how many lunch specials he sells. What is the constant of proportionality in money per lunch special?

Answer 1

Answer: 1/5

Explanation: Since, according to the given figure,

Jake spends money for 60 lunch special= 12 unit

Therefore, In this case, money per lunch= 12/60=1/5

Jake spends money for 45 lunch special=9 unit

Therefore, In this case, money per lunch= 9/45=1/5

Jake spends money for 30 lunch special=6 unit

Therefore, In this case, money per lunch= 9/45=1/5

Again, Jake spends money for 15 lunch special=3 unit

Therefore, In this case, money per lunch= 3/15=1/5

Thus, from the above explanation it is clear that the money per lunch is same for every condition and is equal to 1/5.

Answer 2

Since it's y/x, and x is what you input into the function (and y is what you get out), we get that the amount donated is based off of the lunch specials, so we get y(12)/x(60)=12/60=1/5
