- Well , You can solve this question using two ways. I'm gonna use the both ways to make you clear and the one which you can easily understand , pick up that way and start solving another question as similar as this one.
This method is related to the unitary method. Let's start :
- We're provided - Amount Kelly earns per hour for gardening = $ 12.75 and we're asked to find out the amount she earn if she worked 45.75 hours this month.
- We know , Kelly probably earns more money if she worked 45.75 hours comparison to if she worked 1 hour. So You just multiply 45.75 & 12.75 , you would get $ 583.3125 and that's your final answer.
This method is related to the proportion. If you haven't learned about it yet , use the above way to solve the similar type of questions. Let's start :
- Let Kelly earns X dollars if she worked 45.75 hours this month. [ Now , See the attached picture ]
- Here , we can see the time is increased which implies that money will surely be increased. Such type of proportion is called direct proportion.
- Here , the ratio of time ( in hours ) = 1 : 45.75 and the ratio of amount ( in dollars ) = 12.75 : x . Now , Set up an equation and solve for x :
- Hence , She earned $ 583.3125 .
