A 1-ounce serving of baked potato contains 45.3 calories, and a 1-ounce serving of chicken contains 22.6 calories Estimate to the nearest whole number how many calories are in a meal of 2One-fourth ounces of chicken and a 2One-third ounce baked potato

155 calories

Step-by-step explanation:

Using proportion,

If 1 - ounce serving of baked potato = 45.3 calories

  ounces = ?

=   ÷ 1 * 45.3

=  101.9 calories

1-ounce serving of chicken contains 22.6 calories

ounces = ?

= ÷ 1 * 22.6

= 52.7 calories

∴ Total calories = (101.9 +  52.7) calories

                           = 154. 6 calories which is approximately 155 calories.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
