Respuesta :
If Bill receives $12 for 3 days, then it can also be written as $4 for one day, if we divide by three. If we divide the $40 by the $4 Bill gets in one day, then we will get 10 days. Now for the next part, 3 weeks is 21 days. $4 x 21 days would be $84, which is not enough for the CD. Hope this answer helps! :)
Answer:
Step-by-step explanation:
Bill received $12 to feed a neighbor's cat for 3 days. His pay rate, x would be 12/3 = 4
He is paid $4 for feeding the cat per day.
To earn $40, the number of days that bill would have to work would be 40/4 = 10 days.
The neighbor's family is going on
vacation for 3 weeks next summer. There are 7 days in a week. Converting 3 weeks to days, it becomes 7 × 3 = 21 days.
The total amount of money that Bill will earn in 21 days would be
21 × 4 = $84
Since Bill wants to earn enough money to buy a CD player that costs $89, $84 won't be enough. He still needs $5 more and that would be from 2 more days.
