What system of equations would you use to solve the problem below?
The owner of a bike shop sells tricycles (3 wheels) and bicycles (2 wheels),
keeping inventory by counting seats and wheels. One day she counts 35
seats and 80 wheels. How many of each type of cycle are there?
A. t. b = 80
3t+2b = 35
B. t+b=5
3t+2b = 115
C. t+ b = 35
3t+2b = 80
OD. t+ b = 80
3t+2b=35
