Answer 1

Answer:

$9.50h, $(9.50h +2.20rh)

Step-by-step explanation:

Every hour ----- $9.50

h hours ----- h ×$9.50

Amount of money Mr Smith earns in h hours

= $9.50h

If he fixes a watch per hour, additional income= $2.20h

If he fixes r watches per hour, additional income= $2.20rh

Total income

= $(9.50h +2.20rh)
