Question

Write an equation that represents the total cost of entering the fair

Answer 1

You have to determine an expression that represents the total cost C of entering the fair and buying tickets:

The entrance fee to the fair is $10 → so if you only enter the fair without buying tickets, your total cost would be C=$10

She buys 15 tickets at a price of $t each → to determine the cost of the fifteen tickets you have to multiply the number of tickets by the cost per ticket, 15t

You can express the total cost of entering the fair and buying the tickets as

`C=10+15t`

T evaluate the expression for a ticket price of $1.25 each, you have to calculate the total cost C for t=1.25

`\begin{gathered} C=10+15\cdot1.25 \\ C=10+18.75 \\ C=28.75 \end{gathered}`

The total cost of entering the fair and buying 15 tickets, for a ticket price of $1.25 os C=$28.75
