Claires is paid $90 for five hours of work at this rate how many seconds does it take for her to earn $.25

First find her rate per hour by dividing $90 by 5 hours:

90 / 5 = 18

She makes $18 in one hour.

1 hour = 3600 seconds.

Divide her hourly rate by 3600 to find how much she makes per second:

18 / 3600 = $0.005 per second.

Now divide $0.25 by 0.005 to find the number of seconds needed:

0.25 / 0.005 = 50

It takes 50 seconds.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
