Question

Jordan has 18 pounds. All of the perms are either blue or black and there are six more blue pants and black pants. How many blue pants does Jordan have?

Answer 1

Answer:

12

Step-by-step explanation:

There are 18 pants and the pants are either blue or black. If we represent blue pants as B and black pants as b, this means that:

B + b = 18 _________________________(1)

We are told that there are 6 more blue pants than black pants.  Hence:

B = 6 + b

=> b = B - 6 ________________________ (2)

Putting (2) in (1), we have:

B + (B - 6) = 18

=> B + B - 6 = 18

2B - 6 = 18

2B = 18 + 6 = 24

=> B = 24/2 = 12

This means that there are 12 blue pants.
