Fred earns #$146.78# during the week.

Explanation:

As Fred has worked for #8,4 1/2,3 3/4,7 1/2,4 3/4# hours during the week,

total number of hours worked is

#8+4 1/2+3 3/4+7 1/2+4 3/4#

= #8+4+3+7+4+1/2+3/4+1/2+3/4#

= #26+2/4+3/4+2/4+3/4#

= #26+10/4=26+5/2=26+2 1/2=28 1/2# hours

and at #$5.15# per hour

he earns #28xx5.15+1/2xx5.15#

= #28xx5+28xx0.15+2.575#

= #140+4.20+2.575#

= #146.775~=146.78#

Hence Fred earns #$146.78# during the week.
