Answer:
(a) 30,000 + 14,000x (b) 350y (c) 350y - (30,000 + 14,000x) (d) Yes
Step-by-step explanation:
(a) Total cost = 30,000 + 3,000x + 11,000x = 30,000 + 14,000x
(b) Total revenue = 350y
(c) Total profit = Total revenue - total cost = 350y - (30,000 + 14,000x)
(d) To break even, the total profit of the school should be $0 or more. If they decide to use 5 cars with 4 students assigned to each car, 16 times a year (eight times with two sessions each) then we have a total of 20 students. Using our formula total profit is equal to 350(320) - (30,000 + 14000(5)) = $112,000 - $100,000 = $12,000 profit
The first question is B and the second one is C
Answer:
Step-by-step explanation:
a|c means that c=a*k k is some positive integer. We know that b|c so b| ak and (a,b)=1, so it must be b|k, i.e k=b*r, r is some positive integer number. Now we have that c=abr, so ab| c.
B) if x and x’ are both solution then we have that
mi | x-x’ for every i.
By a) we have that m1m2...mk| x-x’, so x and x’ are equal by mod od m1m2...mk.
The simplified ratio of 15:5 is 3:1, divided both sides by 5
Answer:
-5000 feet
Step-by-step explanation:
32000 - 27000 = 5000, they descended 5000 feet. So the answer is -5000 :))
