last week Joe worked 30 hours and earned $300. at the same rate , how much will hie earn this week if he works 40 hours ?

Respuesta :

If he got $300 dollars working 30 hours in a week. If he works 40 hours, he will get $400 dollars.
Each hour,he earns 10$,Right? So after 30 or 10x30=300,so 10x40=400$
Joe would earn $400,Hope this helps!
