A school typically sells 500 yearbooks in a year for $50 each. The economics class does a project
and discovers that they can sell 125 more yearbooks for every $5 decrease in price. The revenue for
yearbook sales is R(x) = (500+ 125x)(50 - 5x).

answer:2years and 3 months

Step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
