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
Step-by-step explanation:
45.5 percent *130 =
(45.5:100)*130 =
(45.5*130):100 =
5915:100 = 59.15
Now we have: 45.5 percent of 130 = 59.15
Answer:
2 and 11
Step-by-step explanation:
Let's start by calling these two numbers x and y. Now, you can set up the following system of equations:
x*y=22
x+y=13
You can rearrange the following equation to be x=13-y, and substitute into the first.
(13-y)*y=22
-y^2+13y=22
y^2-13y+22=0
y=2 or 11
x=11 or 2
Hope this helps!
Answer:
A. P/2 - L = W
B. 9/5C + 32 = F
Step-by-step explanation:
A. P = 2L + 2W
P = 2(L+W)
P/2 = L + W
(P/2)-L = W
B. C = 5/9(F - 32)
9/5C = F - 32
9/5C + 32 = F
