13.) Which of these is a better deal, on a per ounce basis?

Gala2k [10]

Using proportions, it is found that the better deal, on a per ounce basis, is given by:

A a 30 oz. box of Tasty Wheats for $4.20

<h3>Proportion</h3>

To find the better deal, we use <em>proportions </em>to find the cost per ounce, that is, dividing the cost per the amount of ounces. The <em>better deal </em>is the one with the smaller cost per ounce.

For each option, the costs per ounce are given by:

A a 30 oz. box of Tasty Wheats for $4.20:

$C_a = \frac{4.2}{30} = 0.14$

B a 24 oz. box of Cherry Oats for $3.60

$C_b = \frac{3.6}{24} = 0.15$

C a 42 oz. Box of Giganto Flakes for $6.30

$C_c = \frac{6.3}{42} = 0.15$

D a 42 oz. Box of Giganto Flakes for $6.30

$C_d = \frac{6.3}{42} = 0.15$

Due to the <em>smaller cost</em>, option A is the better deal.

In the local frisbee league, teams have 7 members and each of the 4 teams takes turns hosting tournaments. At each tournament, e

There are 4 teams in total and each team has 7 members. One of the team will be the host team.

Tournament committee will be made from 3 members from the host team and 2 members from each of the three remaining teams. Selecting the members for tournament committee is a combinations problem. We have to select 3 members out 7 for host team and 2 members out of 7 from each of the remaining 3 teams.

So total number of possible 9 member tournament committees will be equal to:

$7C3 \times 7C2 \times 7C2 \times 7C2\\ \\ = 324135$

This is the case when a host team is fixed. Since any team can be the host team, there are 4 possible ways to select a host team. So the total number of possible 9 member tournament committee will be:

$9 \times 324135\\ \\ =2917215$
