Leroy wants to buy a new racing bicycle that costs $168. To earn money, he can either do yardwork for his grandmother or babysit his brother and sister. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting. How much longer will it take him to earn the money if he only does yardwork for his grandmother?

21hrs

Step-by-step explanation:

24 dollars divided by 3 hrs is equal to 8 dollars per hour

so then 168 divided by 8 is 21 and that is how much hours it will take him to earn 168 for a new racing bicycle.
