Michael earns $173.60 for 14 hours. Elena's hourly rate is $0.80 more per hour than Michael's. How much money will Elena earn for working 17 hours? Pls help no trolls

$224.40

Step-by-step explanation:

Divide the total Michael earns ($173.60) by the amount he has worked (14 hours), which gives us the number 12.4, or his hourly wage. Add the 0.80 to receive Elena's hourly wage as it's $0.80 more, which gives us 13.2. Multiply that by 17 (the hours Elena will work) and you'll receive $224.40!! Hope this helped and that I didn't make it too confusing lol
