Question 1056493
.
Tax preparation software is sold in the standard version for $19.95 and the deluxe version for $10 more. 
If a store sold 174 copies of the software for total sales of  $4011.30, how many of each type were sold 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Your equation is

19.95*s + 29.95*(174-s) = 4011.30,

where "s" is the number of standard versions sold.

Or, equivalently,

1995*s + 2995*(174-s) = 401130.

Simplify and solve for s.
