Mr. Smith is paid $9. 50 per hour for fixing watches. Write an expression for the amount of money Mr. Smith earns in h hours. In addition to his hourly rate, Mr. Smith is paid $2. 20 for each watch he fixes. Write an expression for his income if he fixes r watches per hour.

Answer 1

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

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)
