Answer:
620
Step-by-step explanation:
selling 400 doughnuts means selling 800 £ worth of doughnuts. 800 x 0.4 ( to find 40 percent) = 320, + 300 because the the fixed cost = 620. :)
Step-by-step explanation:
I'll do line A for you and you can use the formulas to solve lines B and C yourself, since its good for you to practice doing these questions yourself
a)
The gradient, m, is calculated using m = (y2-y1)/(x2-x1) where x1,x2,y1 and y2 can be any ordered pairs on the line. I'm going to use (4,0) and (7,3) as the 2 points.
m = (3-0)/(7-4) = 3/3 = 1
b)
The y-intercept is where the line intersects with the x-axis. In this case (0,-4)
c)
The equation of a linear line is y=mx+b (or c depending on which country you are from)
y = 1x-4
y=x-4
Now try the other 2 lines yourself!

Answer:
-171
Step-by-step explanation:
Applying PEMDAS (order of operations),
We open the parenthesis first;
-9 - (
)³ × 6
-9 - 3³ × 6
We work on multiplication next;
-9 - 27 × 6 = -9 - 162
finally we do subtraction to get;
-9 - 162 = -171
