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

sveticcg [70]

Answer:

The situation represents the arithmetic sequence

Step-by-step explanation:

∵ The cost of the first night is $240

∵ The cost of each night after the first is $210

∵ The number of nights is x

∵ The total cost of staying at the hotel x nights is y

∴ y = 240 + 210(x - 1)

Put x = 1 , 2 , 3, 4 and then check the type of the sequence

∴ y = 240 + 210(1 - 1) = 240

∴ y = 240 + 210(2 - 1) = 450

∴ y = 240 + 210(3 - 1) = 660

∴ y = 240 + 210(4 - 1) = 870

∵ The difference between each two consecutive terms are constant

(450 - 240 = 210 , 660 - 450 = 210 , 870 - 660 = 210)

∴ The sequence is arithmetic sequence

Your answer is correct, don't worry! To check your answer, just plug in the answer you got with the variable you are supposed to find. Multiplying by a half is like dividing by two. So, 16 divided by 2 is 8. 8 multiplied by 8.25 is 66. I'm jealous of your handwriting.. XD
