Answer:
<u>Part A: Cost for the flooring is $ 4,231.50</u>
<u>Part B: Cost for the flooring is $ 5,531.50</u>
Step-by-step explanation:
Step 1:
Let's calculate the area of the living/dining room, this way:
Area = 26 * 25
Area = 650 ft²
Step 2:
Let's calculate the cost of the flooring if Nancy installs it:
Cost = $ 6.51 * Area of the living/dining room
Cost = 6.51 * 650
<u>Cost = $ 4,231.50</u>
Step 3:
Let's calculate the cost of the flooring if the flooring company installs it:
Cost = $ 8.51 * Area of the living/dining room
Cost = 8.51 * 650
<u>Cost = $ 5,531.50</u>
The first machine works at the rate x = 1 bale/ 25 min.
The second machine works at the rate y = 1 bale/30 min.
The combined rate is
x + y = 1/25 + 1/30 bales/min
= (30 + 25)/(25*30) = 55/750
= 11/150 bales/min
The time for both machines to pick 1 bale of cotton is
(1 bale)/(11/150 bales/min) = 150/11 min = 13.64 min
Answer: 13.6 minutes
Answer:
