Step-by-step explanation:
Money earned by bookstore is $ 12753
<em><u>Solution:</u></em>
Given that college bookstore sold 327 textbooks for $ 39 each
<em><u>To find: Money earned by bookstore</u></em>
From given question,
Cost of 1 book = $ 39
<em><u>Therefore money earned from selling 327 textbooks is given as:</u></em>
Money earned from selling 327 textbooks is calculated by multiplying cost of 1 book by 327
cost of 327 books = cost of 1 book x 327
cost of 327 books = 39 x 327
cost of 327 books = 12753
Thus bookstore earned $ 12753 from selling 327 books

Answer:
m∠A = 116°
Step-by-step explanation:
For better understanding of the solution, see the attached figure of the problem :
The quadrilateral ABCD is inscribed in a circle, Thus the quadrilateral ABCD is a cyclic quadrilateral.
Also, Sum of opposite angles of a cyclic quadrilateral is supplementary.
Now, m∠A = (x - 36)°, m∠B = 28° and m∠D = x°
But, since the sum of opposite angles is 180°
⇒ 28° + x° = 180°
⇒ x = 180 - 28
⇒ x = 152
So, m∠A = (x - 36)°
⇒ m∠A = (152 - 36)°
⇒ m∠A = 116°
