Mom can make 10 brounies in a 12 ounce pacge the bags are sold in one and a half bag how much would she need to make 120

Question is: Mom can make 10 brownies from a 12-ounce package. The brownie mix is also sold in 1 and a half-pound bags. How many bags would be needed to make  120 brownies?

Step-by-step explanation:

As mentioned in question,

10 brownies made from = 12 ounce package

120 brownies will be made from = 10 * 12 packages

now 12 packages will have ounces = 12 * 12 = 144 ounces

We also know that packages are one and a half pounds

Applying conversion factor = 1.5 pound = 24 ounces

Now we can find 144 ounces total requires / 24 ounces

Answer = 6 bags

6 bags of 1.5 pounds will be required for 120 brownies.
