Answer
$$29 \space g \space of \space fiber$$
Work Step by Step
1. Identify the equalities and conversion factors that we will use to solve this problem:
$$100\% \space muffin = 51\% fiber$$ $$6 \space muffins = 1 \space package$$ $$1 \space package = 12 \space oz$$ $$1 \space lb = 16 \space oz*$$ $$454 \space g = 1 \space lb*$$ * Check Table 2.7 (Page 38)
2. Solve the problem using multiple conversion factors:
$$1 \space muffin \times \frac{1 \space package}{6 \space muffins} \times \frac{12 \space oz}{1 \space package} \times \frac{1 \space lb}{16 \space oz} \times \frac{454 \space g}{1 \space lb} = 56.75 \space g$$
$$1 \space muffin = 56.75 \space g$$ $$56.75 \space g \space (muffin) \times \frac{51\% \space fiber}{100 \% muffin} = 28.9425 \space g \space fiber$$
- Rounding of to 2 significant figures:
$$1 \space muffin =29 \space g \space fiber$$
