"bill received $12 to feed a neighbor's cat for 3 days. at this pay rate, how many
days will he have to feed the cat to earn $40? the neighbor's family is going on
vacation for 3 weeks next summer. bill wants to earn enough money to buy a cd
player that costs $89. will he have enough money? explain.

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.
