Question

The doctor recommended that Peter decrease the number of calories consumed from 2,500 to 1,800. By what percent did the number of calories decrease?

Answer 1

Answer:

72%.

Step-by-step explanation:

Setting up the equation, you have 2,500x = 1,800. x represents the percentage that Peter's caloric intake decreased. Then, divide both sides by 2,500 and you get x = 0.72. To get the percentage, multiply 0.72 by 100 and you get 72%
