Respuesta :

Given:

Crystal earns $4.75 per hour mowing lawns.

Let the money earned = M

And the number of hours = H

So, the relation between M and H will be :

[tex]M=4.75\cdot H[/tex]

B. how much does crystal earn if she works 1 hour and 15 minutes? ​

Time = 1 hours and 15 minutes

AS 1 hour = 60 minutes

So,

[tex]H=1+\frac{15}{60}=1+\frac{1}{4}=1+0.25=1.25[/tex]

Substitute with H to find M

So,

[tex]M=4.75\cdot1.25=5.9375[/tex]

So, she will earn $5.9375
