Part B

Question

Carrie is considering three different types of materials for her chairs. Depending on the price she sets for each chair, the costs and revenues for each type of material will generate different costs and revenues for her business.

In the functions in the table, x is the price of each chair. The functions give the revenue (R) and costs (C) that Carrie's business can expect in a year at a given price for the item. Use graphing tools to examine the graphs for each set of equations. Then select the correct answer from each drop-down menu.

Material 1 R(x) = 200,000x - 2,000x2  C(x) = 5,000,000 - 20,000x

Material 2R(x) = 160,000x - 1,000x2  C(x) = 4,000,000 - 10,000x

Material 3 R(x) = 54,000x - 270x2  C(x) = 2,000,000 - 5,000x

Material    (1, 2, or 3)  can deliver the highest profit of about  ($500,000, $2,055,000, $3,225,000 or $4,125,000)  

.

Material  (1,2, or 3)  earns profit for the widest range of prices.

Step-by-step explanation:

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.

7,24
