Deriyan makes $75 for 4 hours of work while Gianna makes $90 for 5 hours of workIf Deriyan works 18.5 hours and Gianna works 19 hours, who makes more money?

Respuesta :

We have the following:

What we must do is calculate the hourly earnings of each, like this

Deriyan

[tex]\frac{75}{4}=18.75[/tex]

Gianna

[tex]\frac{90}{5}=18[/tex]

now we multiply by the number of hours they worked

Deriyan (18.5 hours)

[tex]18.75\cdot18.5=346.875[/tex]

Gianna (19 hours)

[tex]18\cdot19=342[/tex]

Therefore Deriyan made more money in that period of time.
