Sophie and $18 for working 2 1/4 hours how much did she earn per hour

She makes 8 dollars per hour

Step-by-step explanation:

18 ÷ 2.25 = 8

2.25 x 8 = 18

$8

Step-by-step explanation:

2 1/4 hours

= [ ( 2 x 4 ) + 1 ] / 4

= [ 8 + 1 ] / 4

= 9 / 4 hours

For 9 / 4 hours, she gets $18

For 1 hour

= 18 x ( 4 / 9 )

= ( 18 x 4 ) / 9

= 2 x 4

= $8
