So
Total cost of the workbooks is d
And the number of workbooks is t
Therefore d = 95
95=19t
t=95/19=5
5 workbooks
Use inverse proportion ratio: xy=k
(124)(7)=k
k=868 (this is our constant)
now substitute the constant into the inverse proportion ratio knowing the number of workers
28x=868
solve for x by dividing both sides by 28 to find the time it takes to build the house
x=31 days
so it will take 31 days for 28 workers to build the house
