He would make 788 dollars a weak 6.5%of 2200 is 143 so 143+645=788 a week if he sold that much merchandise.

In a 45 - 45 - 90 triangle the two smaller sides are =. So when you use
a^2 + b^2 = c^2, you need a and b both to find the area.
So call both of them = b^2.
Equation and solution
a^2 + b^2 = c^2
b^2 + b^2 = c^2
2b^2 = c^2
c = 24
b = ???
2 b^2 = 24^2
2 b^2 = 576 Divide by 2
b^2 = 288 I'm going to leave this as it is for the moment. You'll see what in a second.
Area of a triangle
Area of a triangle = 1/2 h * b
But the height and base are the 2 smaller equal sides of a 45_45_90 triangle
so h = b
base = b
Area of a triangle = 1/2 b^2 The equalities above tell you that. h and b of the triangle are equal.
Area = 1/2 288 feet^2
Area = 144 feet^2
Answer:
x = (k-c)/8
Step-by-step explanation:
8x+c= k
Subtract c from each side
8x+c-c= k-c
8x = k-c
Divide each side by 8
8x/8 = (k-c)/8
x = (k-c)/8
