Question

when building a house, the number of days required to build is inversely proportional to with the number of workers. One house was built in 124 days by 7 workers. How many days would it take to build a similar house with 28 workers. URGENT!! I WILL CROWN YOU FOR TOP ANSWER!!

Answer 1

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
