Answer:
360
Step-by-step explanation:
Sam obtains a "contribution margin" of $0.50 -0.25 = $0.25 per cookie. That will cover the cost of baking supplies when he sells ...
$90 / ($0.25/cookie) = 360 cookies
Sam needs to sell 360 cookies before he can start making a profit.
_____
If you like, you can find Sam's break-even point by equating revenue and cost. The is the number of cookies Sam must sell for a profit of 0, that is, for non-negative profit.
P = R - C
0 = R - C
R = C
0.50n = 90 +0.25n
0.25n = 90 . . . . subtract 0.25n
n = 90/0.25 = 360 . . . .divide by the coefficient of n
You may notice this is similar to our description above.
It was a lot better then you got me in my life that way
Answer: 26

Answer:
b. -36/77
Step-by-step explanation:
As 0 < x < 
/2 => tan x > 0
As 0< y < /2 => tan y > 0
We have the formula:
As tan x = 1/(cotx) => 
As tan x > 0 => tan x = 8/15
As tan y > 0 => tan y = 4/3
As tan (x-y)=
