Remark
Remove the brackets. Then solve as a normal inequality.
Solution
4(x - 3) - 2(x - 1) > 0
4x - 12 - 2x + 2 > 0 Combine like terms on the left
4x - 2x - 12 + 2 > 0
2x - 10 > 0 Add 10 to both sides
2x > 10 Divide by 2
x > 10/2
x > 5
Answer: B
Discussion
C and D are both true but these questions always assume that you are going to pick the lowest value that will allow the inequality to be true. x> 7 and x>14 will be included in x>5
Use proportions to solve this. Set up the ratios with dollars on the top and pounds on the bottom and then cross-multiply to solve for x. Like this:
. Cross multiplying gives us 800x=168,000. Divide by 800 to get that x = 210. So $300 equals 210 pounds.
