Cody worked 16 hours last week at the grocery store. his friend sophia worked 9 less than twice the number of hours that cody did. if cody made $156.80 and they both make the same hourly rate, how much did sophia make?

After working for 23 hours in grocery store, Sophia made $225.4.

Step-by-step explanation:

The number of hours Cody worked at grocery store = 16 hours

The number of hours Sophia worked  = 2 ( Hours Cody worked) - 9

=  2 ( 16) - 9 = 23 hours

Now, for working 16 hours,Cody earned  = $156.80

So, the per hour earning of Cody =

=

or, the hour earning of Cody = $9.8

⇒Now as Sophia has same hourly rare, so she earns $9.8 per hour.

So, total earning after working  for 23 hours = 23 x ( Earning per hour)

                                                                             = 23 x ($9.8)  = $225.4

Hence, after working for 23 hours in grocery store, Sophia made $225.4.
