Question

Sal made 6 ft of sausage links on Friday morning. He used 3 ft for dinner service on Friday night. On Saturday morning, he made another 6 ft of sausage links and used 9 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night? A. 1 ft B. -1 ft C. 2 ft D. 0 ft

Answer 1

-6 ... even though it is not one of the options would be the correct answer.

Explanation:

In order to solve this problem we can take it one step at a time. Sal started Friday morning with 6ft of sausage

6ft

He used 3ft for dinner on Friday night which means he subtracted 3ft.

6ft - 3ft = 3ft

He made another 6ft Saturday morning which means he added to his existing sausage link.

3ft + 6ft = 9ft

Finally, he used 9ft for dinner Saturday Night which means he subtracted 9ft.

9ft - 9ft = 0ft

Therefore, the net change would be -6 since Sal started with 6ft and ended with 0ft during this time.
