Question

A 50-pound bag of horse feed is a mixture of corn and oats. If 70% of the bag is oats, how many pounds of corn are in the bag? Draw a double number line diagram to show how to find the answer.

Answer 1

Answer: 15 pounds of corn in the bag

Step-by-step explanation: if 70% of the bag is oats, then the remaining 30% must be corn, since oats and corn are the only two ingredients.

We can start by finding 30% of 50 pounds (the weight of the entire bag) to find the weight of the corn:

30% of 50 pounds = 0.3 x 50 pounds = 15 pounds

Therefore, there are 15 pounds of corn in the bag.

Answer 2

15 pounds

Explanation:

50 x .7 = 35

50 - 35 = 15
