Answer:
D
Step-by-step explanation:
First, find out how many more sandwiches he sells after 1 minute. To do this, you can look at the table and see that in 3 minutes, he sells 6 sandwiches. This means that in 1 minute, he will sell 2 sandwiches. In the equation, this will be s = 2t + something. To find out what the "something" is, substitute two values from the table and see what it has to be for the equation to be true.
For example, you can use time = 3 and sandwiches = 19
In the equation this would be
19 = 2 * 3 + something
19 = 6 + something
So that value would be 13.
The linear function is s = 2t + 13

i think it's B, but I'm not sure
The answer is 20. I worked with proportions (making 9/12=15/x)
