I NEED HELP WITH ALGEBRA TWO!
Tickets to a concert are available online for $20 each, plus a one-time handling fee of $1.75. The total cost is a function of the number of tickets bought. What function rule models the cost of the concert tickets ( t )? Evaluate the function for 3 tickets.
A. 20t + 1.75; $25.25
B. 1.75t + 20; $25.25
C. 20t + 1.75; $61.75
D. 1.75t + 20; $61.75

So its 20t+1.75 because each ticket is 20 dollars, so when you substitute 3 into t, the answer is 61.75 

Total cost function for three ticket $61.75 (1.75 + 20t)

Given that;

Cost of each ticket = $20 each

One-time handling fee = $1.75

Find:

Total cost function for three ticket

Computation:

Assume;

Number of ticket = t

So,

Total cost = One-time handling fee + (Number of ticket)(Cost of each ticket)

Total cost = 1.75 + (t)(20)

Total cost = 1.75 + 20t

Number of ticket = 3

So,

Total cost = 1.75 + 20(3)

Total cost = 1.75 + 60

Total cost = $61.75
