Answers

Answer 1

Answer:

Answer:

The average of the John scores is 84.75.

Step-by-step explanation:

Formula of average is given as :

$A=\frac{\text{Sum of all the terms}}{\text{Number of terms}}$

We have:

Test grades of John: 82, 93, 75, and 89

Number of terms - 4

Average of the score of the John;

$a=(82 + 93 +75 + 89)/(4)=84.75$

The average of the John scores is 84.75.

Answer 2

Answer:

First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.

Cameron wanted to buy some pens.They had 18 pens for $ 6.84 for 30 pens for $8.40 which is a better deal?

Answers

$6.84 divided by 18= .38 which means 38 cents per pen

$8.40 divided by 30= .28 which means 28 cents per pen

so $8.40 for 30 pens is a better deal than 18 pens for $6.84 by ten cents.

I would say 18 pens for $6.84 is a better deal because its cheaper.
