Since the trapezoid can be inscribed in a circle, that means angle B + angle D = 180 degree. Since AB is parallel to CD, then angle B + angle C = 180 degree. Therefore, angle D = angle C.

You have to multiply $100 per rocking chair and add it to $40 per bar stool to get our income.

(this is wrong because

SOLUTION:
by putting x = 4y - 1 in the equation x + 2y = 11, we get;
=) 4y - 1 + 2y = 11
=) 6y = 11 + 1
=) y = 12/6
=) y = 2
Now that we got the value of y we can put the value in the equation x = 4y - 1.
=) x = 4(2) - 1
=) x = 8 - 1
=) x = 7
Hence, the value of x is 7 and y is 2.
