A local business kept track of their sales each month for two years. They used this data to create a sales model for their business. The model is y = -0.25x^2 +
6x + 40 hundred dollars per month.
i. Determine when the maximum sales value occurs
ii. Determine the actual maximum sales.
iii. Also, use a graphing calculator to determine when the sales value would be zero
in context of the problem.
HELPPP PLEAS

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

you save $70

discount would be 35% off
