ss7ja [257]
Maximum revenue happens when 950 sandwiches are sold. When more or less sandwiches are sold revenue decreases by a constant amount.

We are told that revenue decreased by $45. We can use this information to calculate the amount of sandwiches.

number_of_sandwiches = total_revenue_change / revenue_change_per_sandwich

number_of_sandwiches = $45 / $0.10
number_of_sandwiches = 450

Number of sold sandwiches is either 450 more or 450 less than the amount of maximum revenue.
Possible numbers of sold sandwiches are:
number = 950 - 450 = 500
number = 950 + 450 = 1400
