Question

A food company reduced the amount of salt in one of their food products from 700 milligrams to 630 milligrams. What is the percent of change in the amount of salt in this product? Classify if is decrease or increase

Answer 1

To find the percent of change, subtract the initial amount from the final amount, divide by the initial amount, and multiply by 100. In this case, the percent of change is 10% and it is a decrease.

Step-by-step explanation:

To find the percent of change in the amount of salt, you need to calculate the difference between the initial amount and the final amount, and then divide that by the initial amount. In this case, the initial amount of salt is 700 milligrams and the final amount is 630 milligrams. The difference is 700 - 630 = 70 milligrams. Now, divide 70 by 700 to get the decimal equivalent: 70/700 = 0.1. Finally, convert to a percentage by multiplying by 100: 0.1 * 100 = 10%. Therefore, the percent of change in the amount of salt is 10%, and since the amount of salt decreased from 700 milligrams to 630 milligrams, it is a decrease.
