Need more info.....
The equation of the dashed line can be found to be y = 2x-1
the shaded are does NOT include the dashed line and is LESS THAN the dashed line
y < 2x-1
Hmmmm 44 440 ?
I THINK this is what you are looking for to answer your Q:

x - 1/6x - 1/4x = flour left to make cupcakes
1 - 1/6 -1/4
12/12 - 2/12 - 3/12 = 7/12
she needs 1/12 for each cupcake .... so 7 cupcakes can be made
n = nickels value = 5n
d = dimes = (53-n) value = 10 ( 53-n) summed, the values = 400
5n + 10(53-n) = 400 solve for 'n'
sqrt(25 - x^2) <====== this term limits the domain....it must be positive (or zero)
so the domain is [-5,5] width = 10
Philip rec'd 8 out of (8+3 ) = 8 /11 of the prize
Terry received 3/ 11 of the prize the difference , 5/11 of the prize = 20 dollars
or 5/11 x = 20 solve for 'x'
