Shara is baking biscuits for a bake sale each Bach 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
Let's assume Shara made x batches of biscuits.
Since each batch makes 75 biscuits, the total number of biscuits from x batches is 75x.
Her friend gave her an additional 60 biscuits, so the total number of biscuits is 75x + 60.
According to the problem, the total number of biscuits is 360.
Therefore, we can write the equation as follows: 75x + 60 = 360.
Subtracting 60 from both sides of the equation, we get: 75x = 300.
Finally, dividing both sides of the equation by 75, we find that x = 4.
Hence, Shara made 4 batches of biscuits for the bake sale.
