Ally and Bella baked some biscuits. Ally ate twice as many biscuits as Bella. If there were 35 biscuits at first and 17 biscuits were left. How many biscuits Ally ate? (Hit: let x= the number of biscuits Bella ate)

Answer 1

Let's assume that Bella ate x biscuits.

Since "Ally ate twice as many biscuits as Bella," this means Ally ate 2x biscuits.

Together, Bella and Ally ate x + 2x = 3x biscuits.

If there were 35 biscuits at first and 17 biscuits were left, this means they ate 35 - 17 = 18 biscuits.

Therefore, 3x = 18.

Simplifying the equation, we have x = 18/3 = 6.

This means Bella ate 6 biscuits.

Since Ally ate twice as many biscuits as Bella, this means Ally ate 2 * 6 = <<2*6=12>>12 biscuits.

Therefore, Ally ate 12 biscuits.
