Question

Kendra spent ⅓ of her allowance on a book and ⅖ on a snack. If she had four dollars remaining after purchasing a book and snack, what was the total amount of her allowance?

Answer 1

Answer: 15$

Explanation:

Given

Kendra spent one-third of allowance on a book and two-fifth on snack.

If she had four dollar remaining after purchase

Suppose x is the original amount

`\therefore x-(x)/(3)-(2x)/(5)=4\\\\\Rightarrow (15x-5x-6x)/(15)=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15`

Thus, 15$ was her total allowance.
