2 tons of sand cost $2,120.00. What is the price per pound?

$0.53 Per Pound.

Work: I did 2 tons divided by $2120. But, before I did the division, I made sure that the 2 tons were in pounds. 1 ton is 2000 pounds, so it's of course 4000 pounds. So, 2120/4000. After the division, I got 0.53 per pound

Check: 0.53 x 4000 = 2120. (Check)

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
