Lee is staying at a hotel. The cost of the first night is $240. The cost for each night after that is $210. Let y represent the total cost of staying at the hotel for x nights. Which type of sequence does the situation represent?

Linear sequence - Cost of staying at the hotel on the first day = $240

Cost of staying at the hotel each day after that = $210

So cost of staying there for x days will be 240 + (x-1) 210

= 210x + 30

The equation is y = 210x + 30

Since the equation is a poynomial equation to the power of

1, it is called a linear equation.
