Question

Q8:

Maria had a package of crackers.
​
​After she ate 8
of the crackers, there ​were 14
crackers left in the package.
​
​Which equation can be used to ​find the number of crackers that were in the package before Maria ate ​the crackers?

Answer 1

The number of crackers that were in the package before Maria ate some, is 22 crackers.

The equation can be written as:

C=L+E

where

C: original number of crackers.

L: number of crackers left in the package.

E: number of crackers eaten.

Explanation:

We can define C as the total crackers that were in the package.

The amount left is L and the amount she has eaten is E.

The amount of crackers left are equal to the original number of crackers less the ones she ate:

`L=C-E\\\\14=C-8\\\\C=14+8\\\\C=22`

The number of crackers that were in the package before Maria ate some, is 22 crackers.

The equation can be written as:

C=L+E

where

C: original number of crackers.

L: number of crackers left in the package.

E: number of crackers eaten.
