Question

the cost of 10 ounces of cheese is 99 cents. what is the price of 10 pounds of cheese in dollars?
$15.84
$31.68
$18.80
$99

Explanation:

Step1: Convert pounds to ounces

We know that 1 pound = 16 ounces, so 10 pounds = 10 * 16 = 160 ounces.

Step2: Find the cost per ounce

The cost of 10 ounces is 99 cents, so the cost per ounce is $\frac{99}{10}$ cents per ounce.

Step3: Calculate the cost of 160 ounces

The cost of 160 ounces is $160\times\frac{99}{10}$ cents. First, calculate $160\times\frac{99}{10}=16\times99 = 1584$ cents.

Step4: Convert cents to dollars

Since 1 dollar = 100 cents, we divide 1584 by 100: $\frac{1584}{100}=15.84$ dollars.

Answer:

$15.84$ (corresponding to the option: $15.84$)
