You can put this solution on YOUR website! [1] A man reduced the price of his goods by 10% ; his sales increased by 25% to $ 180000 per annum.What were they before?
----------------
price * units sold in revenue
-----------------
Let the original sales number be "x".
Let the originial price be "p"
Equation:
(0.90p)(1.25x) = 180000
1.125px = 180000
px = $160,000 (this is the original revenue)
=========================
[2] A man's working hours a day were increased by 20% & his wages per hour were increased by 15%.by how much percentage were his daily earnings increased?
---
Origial earnings were Hours*Wage = hw
------------------------
New earnings are (1.2h)(1.15w) = 1.38hw
--------------------------
His earnings were increased by 38%
===========================================
Cheers,
Stan H.
