Answer:
$3.00
Step-by-step explanation:
Let p = the cost of a pack of pencils
and b = the cost of a binder
Then we have two simultaneous equations.
(1) 2p + 3b = 21.00
(2) 5p + 2b = 25.00
1. Multiply each equation by numbers to give one of the variables the same coefficient.
Multiply (1) by 2 and (2) by 3.This gives
(3) 4p + 6b = 42.00
(4) 15p + 6b = 75.00
2. Subtract (3) from (4)
This gives
(5) 11p = 33.00
3. Solve equation (5) for p
Divide each side by 11
p = 3.00
Each pack of pencils costs $3.00.

Step-by-step explanation:
Answer: Sometimes
Explanation:
Quotient greater than 1:
3/4 divide by 2/3
= 3/4 x 3/2 = 9/8 > 1
4/5 divide by 2/5
= 4/5 x 5/2 = 2 > 1
Quotient less than 1
1/100 divide by 2/10
= 1/100 x 10/2 = 1/20 < 1
1/50 divide by 1/25
= 1/50 x 25/1 = 1/2 < 1
