Answer:

This is an percentage change question, by any chance you have a maths textbook, look for units that contains the topic: Percentage Change. Now, let's get solving! :)

Step-by-step explanation:

Firstly, you must multiply 4.5% with 56. That is: shipping fees x purchase price

That gives ($) 2.52 (this is your answer)

No addition/totaling needed as the question asked ONLY for the shipping fees.

Stay safe and Merry Christmas! :)

In a particular class, exams are worth 50% of the overall grade, quizzes are worth 30% of the overall grade, homework is worth 1
UkoKoshka [18]

<u><em>Answer:</em></u>

His overall grade is 81.9%

<u><em>Explanation:</em></u>

The easiest way to solve this question is by using simple cross multiplication.

<u>1- His overall percentage in exams:</u>

We are given that exams are worth 50% of the grade and that he scored an average of 82.2%

Assume that his overall percentage in exams is e

<u>We can setup the ratio and solve for e as follows:</u>

\frac{82.2}{100}=\frac{e}{50} \\ \\e=\frac{50*82.2}{100}=41.1%

2- His overall grade in quizzes:

<u>We are given that quizzes are worth 30% of the grade and that he scored 74.4%</u>

Assume that his overall percentage in quizzes is q

<u>We can setup the ratio and solve for q as follows:</u>

\frac{74.4}{100}=\frac{q}{30} \\ \\q=\frac{30*74.4}{100}=22.32%

<u>3- His overall grade in homework:</u>

We are given that homework is worth 15% of the grade and that he scored an average of 90%

Assume that his overall percentage in exams is h

<u>We can setup the ratio and solve for h as follows:</u>

\frac{90}{100}=\frac{h}{15} \\ \\h=\frac{15*90}{100}=13.5%

<u>4- His overall grade in class participation:</u>

We are given that class participation is worth 5% of the grade and that he scored a 100% in it

Assume that his overall percentage in exams is p

<u>Since he scored 100%, then he scored the complete worth which is 5%</u>

p = 5%

<u>5- His overall grade in the course:</u>

The student's overall grade in the course is the summation of the above calculated percentages

<u>This means that:</u>

Overall grade = e + q + h + p

Overall grade = 41.1 + 22.32 + 13.5 + 5

Overall grade = 81.92% which is 81.9% approximated to one decimal place

Hope this helps :)
