Siara is baking biscuits for a bake sale. Each batch makes 75 biscuits, and her friend gives her another 60 biscuits. She ends up with 360 biscuits total for the bake sale. Use algebra to solve for how many batches she made

Answer 1

Let's say Siara made x batches of biscuits.
The number of biscuits she made in her batches is 75x.
Her friend gave her 60 biscuits, so the total number of biscuits Siara had is 75x + 60.
This total is 360 biscuits, so 75x + 60 = 360.
Subtracting 60 from both sides of the equation, we get 75x = 300.
Dividing both sides by 75, we find that x = 4.
Therefore, Siara made 4 batches of biscuits. Answer: \boxed{4}.
