At a fast food restaurant, Anas normally works 6.25 hours per day and earns $5.60 per hour. For each hour he works in excess of 6.25 hours on a given day, he is paid 1.25 times his regular rate. If Anas works 10.25 hours on a given day, how much does he earn for that day?

A. $72

B. $63

C. $54

D. $48

E. $35

Changing every decimal into a fraction makes arithmetic easier. Factors cancel.

Regular hours for a workday = 6.25 hrs =

\(6\frac{1}{4} = \frac{25}{4}\) hours

Regular pay: $5.60 per hr =

\(5\frac{3}{5} = \frac{$28}{5}\) per hour

Overtime: working > 6.25 hrs

Overtime rate of pay:

1.25 times regular rate =

\(1\frac{1}{4} = \frac{5}{4} * \frac{$28}{5} = \frac{$28}{4} = $7\) per hour

If Anas works 10.25 hours, how much does he earn for that day?

Extra hours worked: 10.25 - 6.25 =

4 extra hours

Earnings for

extra hrs=

(Overtime rate) * (# of hours)

\((\frac{$7}{hr}) * (4 hrs) = $28\)

Earnings for

regular hours =

(Regular rate) * (Regular # of hrs)

\(\frac{$28}{5hrs} * \frac{25}{4}hrs = $35\)

TOTAL earnings: $28 + $35 = $63

ANSWER B
