Answer:
Step-by-step explanation:
In part (a), we found that the deli needs 7n + 5 slices of bread for n people. Given that this is equal to 110, we have the equation
7n + 5 = 110.Subtracting 5 from both sides of the equation, we have 7n = 10. Dividing both sides by 7, we obtain the solution n = 15. Thus, the number of picnickers is 15.
