16,000 rolls of paper were purchased and 12,500 were sold at $1.79, what is the total ending inventory?
Maslowich
12,500 x 1.79 to find the price but 16,000 - 12,500 to get how many were left. 
12,500 x 1.79 = $22,375 that they made from selling. 16,000 - 12,500 = 3,500 rolls left in the inventory. This question confused me so I just gave both answers.

2x + 8 > 18                      2x+ 8 ≥ 18
2x > 18 -8                            2x ≥ 18 - 8
2x > 10                                 2x ≥ 10
x > 10/2                                  x ≥ 10/2
x>5                                          x ≥ 5

     The answer that combines both inequality is x ≥ 5
