Question

In health class, Karen is learning about making healthy food choices. For a lesson on digestive health, her teacher asks everyone to track how much fiber they eat daily. At breakfast, Karen has a banana. She also has raisin bran cereal, which contains 3.7 grams of fiber. In all, Karen eats 6.8 grams of fiber at breakfast.

Use an equation to find the amount of fiber in the banana.

Answer 1

3.1 grams

Explanation:

You want to use an equation to find the fiber in a banana if, when added to 3.7 grams of fiber in the cereal, the total is 6.8 grams.

Banana

The equation for the fiber in the banana (b) can be ...

b +3.7 = 6.8

The solution is found by subtracting 3.7 from both sides:

b = 3.1

There were 3.1 grams of fiber in the banana.
