Final answer:
The correct equation for Option 1, pricing each ticket at $80 with an additional $10 shipping fee regardless of the number of tickets bought, is y = 80x + 10.
Step-by-step explanation:
The equation for Option 1, where CC buys online tickets for a concert at $80 each with a $10 shipping fee, can be written as a linear equation where y represents the total cost and x represents the number of tickets.
The equation is y = 80x + 10.
This is because each ticket is $80, so the number of tickets times $80 gives the total ticket cost, and the shipping fee is added once, hence the +10 in the equation.
