Question

Siara is baking biscuits for a bake sail. Each batch makes 75 biscuits, and her friend gives her another 60 biscuits. She ends up with 360 biscuits totals. How many batches did she make

Answer 1

Let b be the number of batches Siara made and f be the number of biscuits her friend gave her.
We know that b * 75 + f = 360.
We also know that f = 60.
Substituting the second equation into the first equation, we get b * 75 + 60 = 360.
Subtracting 60 from both sides, we get b * 75 = 300.
Dividing both sides by 75, we get b = 4. Answer: \boxed{4}.
