Jill has a swimming pool in her backyard. it is shaped like a rectangle and measures approximately 16.3 feet wide and 26.2 feet long. it is an average of 5 feet deep. during a few hot weeks during the summer, some water evaporates from the pool, and jill needs to add 8 inches of water to the depth of the pool, using her garden hose. although her water pressure varies, the water flows through jill’s garden hose at an average rate of 10 gallons/minute.
how many liters will jill need to add to her pool to return the water level to its original depth? how many gallons of water is this? reminder: volume = length x width x depth

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
