The graph below shows the value of Edna's profits f(t), in dollars, after t months: graph of quadratic function f of t having x intercepts at 6, 0 and 18, 0 and vertex at 12, negative 36 and passes through 3, 49.5 and 9, negative 27.25

What is the closest approximate average rate of change for Edna's profits from the 3rd month to the 9th month?

−69.75 dollars per month
−11.63 dollars per month
Six dollars per month
Nine dollars per month

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

55 because 55 + 55 = 110 good luck babe
