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.
Let's assume Siara made x batches of biscuits.
The total number of biscuits from the batches is 75x.
Her friend gave her an additional 60 biscuits.
So, the total number of biscuits she has is 75x + 60.
Given that the total number of biscuits is 360, we can set up the equation:
75x + 60 = 360.
Subtracting 60 from both sides of the equation, we get 75x = 300.
Finally, dividing both sides by 75, we find that x = 4.
Therefore, Siara made 4 batches of biscuits. Answer: \boxed{4}.
Let's assume the number of batches Siara made is "x".
Since each batch makes 75 biscuits, the total number of biscuits from the batches is 75x.
Her friend gives her an additional 60 biscuits, so the total number of biscuits she ends up with is 75x + 60.
According to the problem, she ends up with 360 biscuits, so we can set up the equation:
75x + 60 = 360
To solve for x, we need to isolate it on one side of the equation.
First, subtract 60 from both sides of the equation:
75x = 360 - 60
75x = 300
Next, divide both sides of the equation by 75:
x = 300 / 75
x = 4
Therefore, Siara made 4 batches of biscuits for the bake sale.
To solve for the number of batches Siara made, let's represent it as a variable, say "x".
From the problem, we know that each batch makes 75 biscuits. Therefore, the number of biscuits from x batches would be 75x.
Siara's friend gives her an additional 60 biscuits. Adding this to the number of biscuits from the batches would give us a total of 360 biscuits. So, we can set up the equation:
75x + 60 = 360
First, we'll subtract 60 from both sides of the equation:
75x = 360 - 60
75x = 300
Now, to solve for x, we'll divide both sides of the equation by 75:
x = 300/75
x = 4
Therefore, Siara made 4 batches of biscuits for the bake sale.
