Question

Lani's mother gave her and her two sisters $21 to spend at the movies. If each girl gets the same amount, how much do they each have to spend?

Answer 1

each sister gets 21 dollars, so there are three sisters there fore 21*3 equals 63

Answer 2

$7.

Explanation:

We have been given that Lani's mother gave her and her two sisters $21 to spend at the movies.

We are asked to find the amount each girl have to spend.

To solve our given problem, we will divide $21 with 3 as Lani and her two sisters would be 3 persons.

`\text{Amount that each girl have to spend}=(\$21)/(1+2)`

`\text{Amount that each girl have to spend}=(\$21)/(3)`

`\text{Amount that each girl have to spend}=\$7`

Therefore, each girl gets $7 to spend.
