Answer:

we conclude that the cost of 100 pencils = $11

Step-by-step explanation:

Brianna can buy 14 pencils for $1.50 at the school store.

unit rate = $1.50 / 14 pencils

= 0.11 USD per pencil

Thus,

The cost of 1 pencil = $0.11

The cost of 100 pencils = $0.11 × 100

= $11

Therefore, we conclude that the cost of 100 pencils = $11

7. Evaluate 4P2 O 22 O 12 O 14 5

Reika [66]

Answer:

Step-by-step explanation:

To evaluate 4P2, we will use the permutation formula as shown;

nPr = $\frac{n!}{(n-r)!}$

4P2 = $\frac{4!}{(4-2!}$

$= \frac{4!}{2!} \\= \frac{4*3*2!}{2!}\\ = 4*3\\= 12$

4P2 = 12
