First, count the sum of price for 3 pencils
pencils = 3 × price per pencil
pencils = 3 × 0.99
pencils = 2.97
The price of three pencils is $2.97

Second, count the sum of price for 2 packs of paper
paper = 2 × price per pack
paper = 2 × 2.50
paper = 5.00
The price of two packs is $5.00

Third, sum the prices and tax
price = paper price + pencil price
price = 2.97 + 5.00
price = 7.97

tax = 4% × 7.97
tax = 0.04 × 7.97
tax = 0.3188

total = 7.97 + 0.3188
total = 8.288

Total pay is $8.288, she has enough money to pay it.

Fourth, calculate the change
change = 20 - 8.288
change = 11.712

The change would be $11.71

A number k is greater than 3. Which of the following is true about 승 ? 1 It is between 3 3 It is equal to 1 It is greater than 1
Alekssandra [29.7K]

If the number k is greater than 3, we have the following inequality:

k>3

In order to evaluate k/3, let's divide the inequality by 3:

\begin{gathered} k>3 \\ \frac{k}{3}>\frac{3}{3} \\ \frac{k}{3}>1 \end{gathered}

So the expression k/3 is greater than 1, therefore the correct option is D.

Mr. Carson wants to give three pencils to each of his students. There are 26 students in Mr. Carsons class. Boxes of pencils eac
Rasek [7]
Since there are 26 students in Mr. Carson's class, and each kid gets 3 pencils, that means we will multiply 26 and 3, in which we get 78. Now, since boxes of pencils only contain a dozen, which is 12 pencils, we will divide 78 by twelve, in which we get 6.5 boxes. You can't buy half a box, so he will need 7 boxes, since having 6 boxes means that you don't have enough pencils.

Hope this helps!
