Answer:
A. -8<=y<=6
Step-by-step explanation:
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
Answer:
174.50
Step-by-step explanation:
first order the numbers from least to greatest then find the middle digit. if there are two, add them together, then divide them by 2. if there's only one, that is your median.
7 7/8 - 3 1//4 = 49/8 - 3/4 = 49/8 - 6/8 = 43/8 (or 5.375)
