A shoe factory produces 1.81 × 104 pairs of shoes each month. Estimate how many pairs of shoes the factory will produce if it maintains that rate for 10 years. (There are 1.2 × 102 months in 10 years.)
1. Estimate each coefficient: 1.81 ≈ 2
1.2 ≈ 1
2. Write the product: (2 × 104)(1 × 102)
The shoe factory would make approximately
____ ×106 pairs of shoes in 10 years.
