Answer: B. Absolute value function
"The two pumps working together would pump out water at a rate of 100 gallons per minute. To determine the time it takes to completely pump out the water from the basement, we need to determine the volume of the water in the basement. The dimensions of the basement is 40 feet by 50 feet (given elsewhere) while the depth of the water is said to be 16 inches. From these dimensions, we can calculate for the volume as follows:"
V = length x width x depth
length = 50 feet
width = 40 feet
depth = 16 inches ( 1 foot / 12 inches ) = 1.33 feet
V = 50 x 40 x 1.33 = 2666.67 ft^3 = 19948.05 gal
Time = V / rate
Time = 19948.05 gal / 100 gal / min
Time = 199.48 min
Since you are writing an inequality, you will want to look for the sign you need to write in place of the equal sign. Since, in the context, it states "less then 60 dollars", you will need to use the < sign. Next, you will need to find the main value, 200, and put it on the left sign of the inequality sign. Since you pay the friend 12 dollars per week, you will want to subtract 12x from 200. Your equation should now be :
200 - 12x < 60
You would then solve. help any?
