Answer 2

ANSWER
The bag of dog food remaining is


`3 (4)/(5) \: pounds`

Step-by-step explanation

The bag of dog food bought is


`= 25 \: pounds`

The quantity consumed in the first month is

`= 10 (2)/(5) \: pounds`


`= (52)/(5) \: pounds`


The quantity consumed in the second month is


`=10(4)/(5) \: pounds`


`= (54)/(5) \: pounds`
The total quantity consumed is

`= (52)/(5) + (54)/(5)`



`= (106)/(5) pounds`


The quantity remaining can be calculated by subtracting the quantity consumed from the original quantity.


Quantity of dog food remaining is

`= 25 - (106)/(5)`

`= (25)/(1) - (106)/(5)`
We collect LCM to get,

`= (125 - 106)/(5)`



`= (19)/(5)`


`= 3 (4)/(5) \: pounds`
