Question

You have $2.10 and would like to buy some rolled oats. If a pound costs $4, how many ounces can you buy?

Answer 1

EXPLANATION

Given that we have $2.10 and we would need to buy some rolled oats.

If a pound costs $4, we can compute the ounces that we can buy by applying the unitary considering that 1 pound = 16 ounces

`\text{?ounces}=\frac{1\text{ pound}}{4\text{ dollars}}\cdot2.10\text{ dollars}\cdot\frac{16\text{ ounces}}{1\text{ pound}}`

Multiplying numbers and simplifying:

`\text{?ounces}=(33.6)/(4)\text{ounces}=8.4\text{ ounces}`

Answer: We could buy 8.4 ounces
