Let
x = the number of Standard units sold
y = the number of Enhanced units sold
Total of 24 units was sold:
x + y = 24
The cost of all 24 machines is $7,575 altogether:
275x + 340y = 7575
We have the following system of equations:
x + y = 24
275x + 340y = 7575

........
x = 9 Standard units
y = 15 Enhanced units
The value for 9 Standard units is:
275*9 = $2,475
The dollar value for the sales of the Standard model is $2,475.
