Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.

C(P(x)) = 0.9x – 150

Step-by-step explanation:

Let x be the original price of the article,

Since, the discount percentage = 10 %,

Thus, the price of the article after getting discount of 10 % = (100-10)% of the original price of the article

= 90% of x

= 0.9x

Now, there is a coupon of $ 150,

Hence, the final price of the article = 0.9x - 150

⇒ C(P(x)) = 0.9x - 150

Which is the required composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
