Al has twice as many cards as Bob, and Jane has three times as many cards as Bob. Together, they have 372 cards. How many cards

Musya8 [376]

Answer: Bob has 62 cards.

All has 124 cards.

Jane has 186 cards

Step-by-step explanation:

Let x represent the number of cards that Bob has.

Al has twice as many cards as Bob. It means that the number of cards that All has is 2x.

Jane has three times as many cards as Bob. It means that the number of cards that Jane has is 3x.

Together, they have 372 cards. It means that

x + 2x + 3x = 372

6x = 372

x = 372/6

x = 62

The number of cards that Al has is

2 × 62 = 124

The number of cards that Jane has is

3 × 62 = 186

<u>Answer</u>:

18 clips for $7.38 is the best value deal.

<u>Step-by-step explanation:</u>

An office is restocking office supplies. The table below shows the cost for the number of boxes of paperclips. We need to find what is the best value is.

To find the best value for money we can check the price of each paperclip.

To check the price of each paper clip we can use the following formula:

$\text{Price of each paper clip} =\frac{\text { price of the box }} {{\text {number of clips in the box }}}$

Now we can calculate the best value deal as follows:

$\text{Price of each clip is box 1}=\frac{7.38}{18}=0.41$$

$\text{Price of each clip is box 2}=\frac{15.39}{27}=0.57$$

$\text{Price of each clip is box 3}=\frac{13.50}{30}=0.45$$

$\text{Price of each clip is box 4}=\frac{18.36}{36}=0.51$$

$\text{Price of each clip is box 5}=\frac{18.80}{40}=0.47$$

So, from looking at the prices of each paperclip we can conclude that the 18 clips for $7.38 is the best value deal.
