A jar of jelly beans that weigh 4.25 ounces costs 2.89. what is the cost of one ounce of jelly

EastWind [94]

You have:
Cost in dollars --> $2.89 
Total ounces --> 4.25 

But you want to know the per unit cost for *1* ounce. 

You have the right method. You want cost ($) per ounce so put the price over the amount in ounces. 
2.89 / 4.25 = x / 1 

If you notice, since the denominator is 1, this is simply: 
x = 2.89 / 4.25 

So the unit cost is just $2.89 divided by the number of ounces (4.25). 

Plug that into your calculator and you get: 
0.68 

That's in dollars. So if you want it in cents, move the decimal point 2 places to the right. 

Answer: 
$0.68 per ounce 
or 
68 cents per ounce

Sarah’s mom took 3 hours to clean, but when Sarah helped, it took them 2 hours to clean. How many hours will it take Sarah to cl

Aleonysh [2.5K]

Answer:

It takes them 1.875 hours.

Step-by-step explanation:

Here, the job is cleaning the house.

Mom does 1 job in 3 hours.

In 1 hour, mom does 1/3 of the job.

Dad does 1 job in 5 hours.

In 1 hour, dad does 1/5 of the job.

Mom and dad working together do the job in x hours.

In 1 hour, mom and dad together do 1/x of the job.

1/3 + 1/5 = 1/x

5/15 + 3/15 = 1/x

8/15 = 1/x

8x = 15

x = 15/8 = 1.875

Answer: It takes them 1.875 hours.
