How many counselors and how many aides should the camp hire to minimize cost ?

( 1 )

Step-by-step explanation:

if the minimum is 20 than that is the least cost affective and 8 counselors and 12 aides make up 20 staff but 8 divided by 2 is 4 and 4 multiplied by 3 is 12 to accommodate the 3 aides to every 2 counselors  

answer: a.   one is a factor of every whole number since every number is divisible by itself.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
