Carol is going to be away on vacation for a couple of days. She does not know how long she will be gone. Carol, however, knows that $250 will be enough for the caretaker to feed the cats, Rover and Bobo, while she is away.

$150

Step-by-step explanation:

Here is the question again I will bold everything that is important.

Rover eats 3/4 of a can of cat food each day and Bobo eats 1/2 of a can of cat food each day.

Cat food costs $5.00 for three cans. It is only sold in 3-can packs.  

How much does it cost Carol for a 60-day supply of cat food for her two cats?

Ok now that the important stuff is highlighted we can now start the math.

So first we add together the amount of food eaten everyday by both cats.

3/4=.75

1/2=.5

.75+.5=1.25

Ok now that we have the total food eaten everyday we can proceed.

ok so we know that the total food eaten by both cats every day is 1.25 cans but we need to get as close to 3 cans as possible.

1.25x2=2.50

ok we are now at 2.5 cans but that for every other day so they eat 2.5 cans every two days but we will need to buy more food. so lets go to your favorite store and buy some. CACHING. ok we are out of the store now more math.

ok so how many meals can we get out of this buy. lets find out.

2.5 cans every other day so we can give the leftover .5 of a can to Bobo and we can open a new can for Rover.

ok after this meal we have 1.25 cans left so tomorrow we can give that to them.

ok its tomorrow now and its feeding time so lets feed them no need to buy food because we have the perfect amount left.

so we went through 6 cans in 4 days so how much do we go through in 60 days. well lets find out

we will do this by dividing 60 by 4

60/4=15

so we now need to multiply 15 times 6 because that will give us the answer

15x6=90

ok now that we know that we go through 90 cans in 60 days we can finally find out how much it will cost us so we will find that out like this

we will divide 90 by 3 because that is the amount of cans we get every purchase

90/3=30

now we will multiply 30 times 5 because that is the amount of money needed to purchase

30x5=150

ok so we now have our answer it is $150

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
