Fred earns $$ 146.78$ $$146.78$ during the week.

As Fred has worked for $8, 4 \frac{1}{2}, 3 \frac{3}{4}, 7 \frac{1}{2}, 4 \frac{3}{4}$ $8,4 1/2,3 3/4,7 1/2,4 3/4$ hours during the week,

total number of hours worked is

$8 + 4 \frac{1}{2} + 3 \frac{3}{4} + 7 \frac{1}{2} + 4 \frac{3}{4}$ $8+4 1/2+3 3/4+7 1/2+4 3/4$

= $8 + 4 + 3 + 7 + 4 + \frac{1}{2} + \frac{3}{4} + \frac{1}{2} + \frac{3}{4}$ $8+4+3+7+4+1/2+3/4+1/2+3/4$

= $26 + \frac{2}{4} + \frac{3}{4} + \frac{2}{4} + \frac{3}{4}$ $26+2/4+3/4+2/4+3/4$

= $26 + \frac{10}{4} = 26 + \frac{5}{2} = 26 + 2 \frac{1}{2} = 28 \frac{1}{2}$ $26+10/4=26+5/2=26+2 1/2=28 1/2$ hours

and at $$ 5.15$ $$5.15$ per hour

he earns $28 \times 5.15 + \frac{1}{2} \times 5.15$ $28xx5.15+1/2xx5.15$

= $28 \times 5 + 28 \times 0.15 + 2.575$ $28xx5+28xx0.15+2.575$

= $140 + 4.20 + 2.575$ $140+4.20+2.575$

= $146.775 ≅ 146.78$ $146.775~=146.78$

Hence Fred earns $$ 146.78$ $$146.78$ during the week.

Fred worked these hours during the week: 8,412,334,712,4348, 4 1/2, 3 3/4, 7 1/2, 4 3/4. If he is paid $5.15 per hour, how much did he earn?
