(1) At the start of her shift at Midtown Bakery, Megan made some batches of cookies that called for 3 cups of flour each. Then, she used the remaining 8 cups of flour she had to mak a pan of muffins. She started her shift with a 20-cup bag of flour.

(1) Which equation can you use to find how many batches of cookies, x, Megan made?
3(x + 8) = 20
8(x + 3) = 20
3x + 8 = 20
8x + 3 = 20

The correct equation to use to find how many batches of cookies, x, Megan made is:

3x + 8 = 20
