Answer:

21 questions were correctly answered

Step-by-step explanation:

If one scores an 84% on a quiz, that means that as an expression out of 100, a person has gotten 84 correct. To find how much the 84% equates to, one must convert the percent to a decimal. This means that one must divide the 84 by 100. After doing so, multiply the result by the number of questions on the quiz. The value attained will be the number of questions answered correctly.

Convert percent to decimal:

84% / 100 = 0.84

Multiply by the number of questions to find the amount answered correctly:

25 * 0.84 = 21

84% of 25 is 21

The maximum score is 100%, 100÷25= 4, meaning each question was 4 points or 4% of the total grade 84÷4=21 .

prisoha [69]

The total electric energy bill for the month is $\$104.24$

<u>Solution: </u>

Given that

Electric energy consumed by family in a month = 1303 kWh

Power Company charges $\$0.08$ per kilowatt hour

Need to calculate total electric energy bill for the month.

Price of 1 kilowatt hour = $\$0.08$
