Question 39052
1).Jim is able to sell a hand-carved statue for $670 which was a 35% profit over his cost. How much did the statue originally cost him?
Let original cost be "x"
Then x+0.35x=670
   1.35x=670
      x= $496.30

2).The sales price of a car is $12,590, which is 20% off the original price. What is the original price?

Let the original price be "x"
Then x-0.20x=12590
        0.80x=12590
        x=$15737.50 


3). Solve the following equation for A : 2A/3 = 8 + 4A 
Multiply thru by "3" to get:
2A = 24+12A
-10A=24
A=-12/5=-2.8
