Answer:
The profit is $24
Step-by-step explanation:
Step one:
given the expression for the profit made as
![1.25p-0.75p,](https://tex.z-dn.net/?f=1.25p-0.75p%2C)
we are told that p is the number of pens, hence for p= 48 by substituting into the expression we can find the profit as
Step two:
Profit= 1.25p-0.75p,
Profit= 1.25(48)-0.75(48),
Profit= 60-36
Profit=24
D. x + (-x) = 0
That is the answer because if you are x feet above sea level, to get back to sea level, which equals zero (0), you need to go down the same amount you went up (x), so you need to go down x feet (-x).
Answer:
A
Step-by-step explanation
You can divide 6x,9y and -15 by 3
6x/3=2x
9y/3=3y
-15/3=(-5)
Combine them to get the factored form of 6x+9y-15:
3(2x+3y-5)
Work out 10% - 360/10 = 36
and then divide it by 2 to find 5% (half of 10%!) - 36/2 = 18
Hope this helps :)
