____ answer

1 answer

Let x be the number of batches Siara made.
She made 75 * x biscuits in total.
Her friend gave her an additional 60 biscuits.
The total number of biscuits she ended up with is 75 * x + 60 = 360.
Subtracting 60 from both sides of the equation, we have 75 * x = 300.
Dividing both sides of the equation by 75, we get x = 4.
Therefore, Siara made 4 batches of biscuits. Answer: \boxed{4}.
