Lisa earns $40.80 for 4 working hours on the days that she works part-time. she earns $81.6 for 8 working hours that she works full-time. how much money does earn per hour?

ANSWER: 10.2

You could either divide 40.80 by 4 OR 81.6 by 8. BOTH would equal the dividend of 10.2.

It says she earns $81.6 for 8 working hours that she works full-time.

Diving 81.6 by 8 would equal 8 would equal the answer (10.2).

If you want to know why divide by 8?  8 = 8 working hours she works full-time.

Hope this helps! :)

I’ll you if you answer my questions!
