The students at Porterville Elementary sold raffle tickets, each for the same price, for a fundraiser. The equation below shows how much money was raised with t tickets sold.

Question

$885 = $15t

What is the unit rate in the equation above?
A.
$870 per raffle ticket
B.
$15 per raffle ticket
C.
$59 per raffle ticket
D.
$885 per raffle ticket

Answer 1

To find the unit rate in the equation \( 885 = 15t \), we need to understand what the variables represent.

In this equation, \( t \) represents the number of raffle tickets sold, and the equation reflects that the total amount of money raised (which is $885) is equal to the number of tickets sold \( t \) multiplied by the price per ticket (which is $15).

The unit rate describes how much money is raised per one ticket sold. This is simply the coefficient of \( t \) in the equation, which is the price of each ticket.

Since the price for each ticket is given as $15, the unit rate is:

B. $15 per raffle ticket
