Answer:
B. No, Marcus did not write the system of equations correctly. Each adult ticket was $16 and each student ticket is $9.
Explanation:
If you multiply the adults and students with the cost of the tickets in the first bus you would end up with the equations, 16x3=48 and 6x9= 54. Then you add the totals ($48+$54) and get $102 for the first bus. The next bus's equations would be, 16x2=32 and 9x7=63 then you add the totals ($32+$63) and get $95.
