## Algebra 1: Common Core (15th Edition)

This problem involves a unit conversion. We know that there are 365 days in a year. Thus, we find: $\frac{. 25 oz}{day} \times \frac{365 days}{year} \times \frac{1 pound}{16 oz}=5.70$ pounds per year. Note, we need to cancel out the unit of ounces, so we multiply 2.25 ounces by a fraction with ounces in the denominator. We also need to cancel out the unit of days, which is in the denominator of the first fraction, so we multiply by a fraction with days in the numerator.
