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. (1 point)
Let's say Siara made x batches of biscuits.
So the total number of biscuits she made from the x batches is 75x.
Her friend gave her another 60 biscuits.
The total number of biscuits Siara ends up with for the bake sale is 360 biscuits.
So, 75x + 60 = 360.
By subtracting 60 from both sides of the equation, we get 75x = 300.
By dividing both sides of the equation by 75, we find that x, the number of batches Siara made, is 4. Answer: \boxed{4}.
