Jerry and thomas own a cleaning business. thomas cleans a house in 2 1/2 hours . jerry cleans a house in 3 1/4 hours. how much longer does it take jerry to clean a house than thomas

Jerry takes 0.75 hours or hours more to clean house than thomas

Given that Jerry and Thomas own a cleaning business

Thomas cleans a house in hours and Jerry cleans a house in hours

To find: Number of hours more Jerry takes to clean than thomas

Number of hours more Jerry takes to clean than thomas = time taken by Jerry - time taken by thomas

Time taken by Jerry =

Time taken by Thomas =

Substituting the values in above formula,

Number of hours more Jerry takes to clean than thomas =

On solving we get,

Thus Jerry takes 0.75 hours or hours more to clean house than thomas

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

60 for the first and 130 for the second
