Answer:
13
Step-by-step explanation:
If Chad had 7 sandwiches and that was 6 fewer than the amount Sarah has then Sarah made 6 sandwiches. The working is as follows :
Chad = 7 sandwiches (6 fewer than Sarah)
Sarah = ?
Sarah = 7 + 6 = 13 sandwiches.
In order for Chad to have eaten that many sandwiches, Sarah would have had to have made 13 sandwiches.
Sarah made x number of sandwiches and Chad ate 7 out of it.
The 7 that Chad ate remained 6 sandwiches out of the total that Sarah made.
The number of sandwiches Sarah made is therefore:
= Number that Chad ate + Number that was left
= 7 + 6
= 13 sandwiches
In conclusion, Sarah made 13 sandwiches
