Answer:

50 for $4.75

Step-by-step explanation:

First step is to determine the unit cost of each pencil:

price of pack / number of units = cost per pencil

1. $2.19 / 12 = $0.1825

2. $3.99 / 40 = $0.09975

3. $4.75/ 50 = $0.095

4. $10 / 100 = $0.10

The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.

Leona [35]

Answer:

4.5 ft

Step-by-step explanation:

Let us assume the height of the taller brother be x

And, the height of the shorter brother be y

Now according to the question

x - y = 0.833

Now solve these two equations

2x = 11.666
