Question 67436
You have set it up correctly but there is a little problem with the math.
If x represents the number of Smart Cards issued in 2001, then:
x + 1.17x = 500 (in millions) Simplifying this:
2.17x = 500 Multiplying both sides by 100.
217x = 50000 Divide both sides by 217
x = 230.4147...millions.  Round to the nearest million.
x = 230 million.
