Roberta makes a $9 an hour plus a 12.5% commission selling jewelry how much does she earn on a 8 hour shift which she sells $380 worth of jewelry

The amount Roberta makes an hour is $119.5

Explanation:

Let the number Roberta makes be x hours.

Amount earned in x hours shift - 9*x + 12.5% of the amount of jewelry sold.

Number of hours worked by Roberta if 9 hours and jewelry worth $380 is sold by her.

Substituting the values:

Amount earned in an 8 hour shift = 9*8 + 12.5% od 380

= 72 + 0.125 * 380 (12.5% = 0.125)

= 12 + 47.5

= 119.5

$119.50

Explanation:

12.5x = 9x100

12.5x = 900

12.5x/12.5 = x

900/12.5 = 72

x = 72

12.5% * $380 = $47.50

72.00 + 47.50

$119.50
