Answer:
295 SUVs were sold, and 215 passenger vehicles.
Step-by-step explanation:
Let s and p represent the number of SUVs and p the number of passenger cars.
Then s = p + 80 and s + p = 510.
Substitute p + 80 for s in the second equation, obtaining:
p + 80 + p = 510, or:
2p = 430
Dividing both sides by 2 isolates p: p = 215.
Since s = p + 80, we add 80 to 215 here, obtaining s = 295.
295 SUVs were sold, and 215 passenger vehicles.
