I have to get 2 equations from this and use the substitution or elimination method

- Pre-Calculus -
**drwls**, Thursday, July 24, 2008 at 7:22pmThe first equation would be

3000 C + 5000 T = 137,000,000 (total sales)

The second equation would be

3000*.20*C + 5000*.30*T = 27,000,000 (profit)

This can be rewritten

600 C + 1500 T = 27,000,000

Now solve those two equations for C and T, the number of cars and trucks sold, using either method.
