It would take 48 days for 5 men to build a house.
(a) How much longer would it take if only 4 men built the house?
The number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
W=(1/n)
It would take 48 days for 5 men to build a house. Thus, the work done by one man in one day is,
W=1/(48*5)
W=1/240
Thus, one man take 240 days to build a house. The time it takes when only 4 men works to build the house,
t=240/4
t=60
Hence, the number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.

Gavin is selling water bottles at a baseball game to help raise money for new uniforms. before the game, he buys 75 water bottles for a total of $25. at the game, he sells all of the bottles for $1.20 each. how much profit does gavin make?
The amount of profit Gavin made in selling the water bottles at the base ball game is $65.
How to find profit?
He bought 75 bottle water for a total of $25.
He sales all of the bottles for $1.20 each.
Therefore,
profit = selling price - cost price
Hence,
cost price = $25
selling price = 1.20(75) = $90
