Afood truck owner has determined that her maximum revenue occurs when she sells  950950950sandwiches per month. for every sandwich above or below  950950950  that she sells, her revenue decreases by  \$0.10$0.10dollar sign, 0, point, 10. which of the following could be the number of sandwiches sold in a month if the owner's revenue decreased  \$45$45dollar sign, 45  from the maximum? round the answer to the nearest whole number.

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
