Question

an 8-pound bag of sand costs $3.21. what is the unit price, rounded to the nearest cent? $\square$ per pound submit

Explanation:

Step1: Define unit price

Unit price is total cost divided by total weight. So we calculate $\frac{3.21}{8}$.

Step2: Perform division

$3.21\div8 = 0.40125$.

Step3: Round to nearest cent

A cent is two decimal places. Rounding $0.40125$ to two decimal places, we look at the third decimal which is 1, so we don't round up. So it's $0.40$.

Answer:

$0.40$
