D.No, because the total earned is $1255.70 per month.
Step-by-step explanation:
Essentially if your cost is 1543 a month, you simply wouldn't be able to afford it.
If you plug in 7.25 and 40 (you get 290) . With this information we plug it into weeks. In a month there are approximately 4.345 weeks (you can just times 290 by
