Carly buys t play tickets at $14.50 per ticket and t choir concert tickets at $5.50 per ticket. What is the cost for play ticket
Step2247 [10]

Answer:

20t

Step-by-step explanation:

Carly buys t play tickets at $14.50 per ticket and t choir concert tickets at $5.50 per ticket. What is the cost for play tickets and choir concert tickets.

The cost of the play tickets is the number of play tickets multiplied by the cost of each ticket.

Play tickets: number of tickets: t; cost of each ticket: $14.50

Cost of play tickets: 14.50t

The cost of the choir tickets is the number of choir tickets multiplied by the cost of each ticket.

Choir tickets: number of tickets: t; cost of each ticket: $5.50

Cost of choir tickets: 5.50t

Total cost of play tickets and choir tickets:

14.50t + 5.50t = 20t

HELP for (ii)…..how do we find a?
Mariana [72]

By using the information given on the graph, we can see that a = 3.

<h3>How to find the value of a?</h3>

Here we have an exponential of the form:

y = p*a^x

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

4 = p*a^0\\\\36 = p*a^2

From the first equation we get that p = 4, replacing that on the second one we get:

36 = 4*a^2\\\\36/4 = 9 = a^2\\\\\sqrt{9} = 3 = a

So we conclude that a = 3.
