If Samantha earns $225.00 for 6.25 hours of work, how many must he work to earn $918.00?

(225/ 6.25) X x = 918 

36.00 X x = 918 

x = 918/36 

x = 25.5 hours.  

n = 6.25*918/225 = 25.5 hours

Heya,

If Samantha earns $225.00 for 6.25 hours of work her hourly rate is 225.00/6.25 $ per hour

let x = the number of hours she has to work to earn $918.00

x * the rate per hour = 918

x(225.00/6.25) = 918

by solving we find

by solving we find

x = 25.5 hr

he or she , big difference , 25.5 hours .

My process for solving this would be first to find the hourly rate.

225 / 6.25 ; multiply top and bottom by 4

900 / 25 ; multiply top and bottom by 4

36 / 100 = $3.60 / hour

3.60 looks like it has a factor of 9, so it's an easy division to do 900 / 3.60 = 100 / 0.4 = 250

250 hours accounts for $900, leaving $18 left over.  18/3.60 = 5, so 5 more hours of work

250 + 5 = 255

Of course, with a calculator or computer handy, someone can just type "918 / (225 / 6.25) ="

If Samantha earns $225.00 for 6.25 hours of work, 

her hourly rate is $36. (225/6.25=36). 

To earn $918.00, she will have to work 25.5 hours. (918/36 = 25.5)

225/6.25= 918/x

225x = 5737.5

 x = 25.5 hours  Answer//

225/6.25 = 918/x

225x = 918(6.25)

225x = 5737.5

x = 25.5

She earns 225.00/6.25 = $36 pr hour and so 918/36 = 25.5 hours

Answer is 25.5

  Samantha earns $225.00 for 6.25 hours of work.

That means :

Earning in 6.25 hours = 225

Earning in 1 hour = 225 / 6.25

= 36

Thus Samantha earns $ 36 for 1 hour of work.

We have to find how many hours must he work to earn $ 918.00.

Let us assume that , To earn $ 918 .00 , He has to work x hours.

So, x * 36 = 918

x = 918 / 36

= 25.5

Hence Samantha must to work 25.5 hours to earn $ 918.00.
