1.)
Between year 0 and year 1, we went from $50 to $55.
$55/$50 = 1.1
The price increased by 10% from year 0 to year 1.
Between year 2 and year 1, we went from $55 to $60.50.
$60.50/$55 = 1.1
The price also increased by 10% from year 1 to year 2. If we investigate this for each year, we will see that the price increases consistently by 10% every year.
The sequence can be written as an = 50·(1.1)ⁿ
2.) To determine the price in year 6, we can use the sequence formula we established already.
a6 = 50·(1.1)⁶ = $88.58
The price of the tickets in year 6 will be $88.58.
Step-by-step explanation:
c^2 = a^2 + b^2

6 seconds = 540 m
-----------------------------
Find 1 second:
-----------------------------
6 sec = 540 m
1 sec = 540 ÷ 6
1 sec = 90m
-----------------------------
Find 4 seconds:
-----------------------------
1 sec = 90m
4 sec = 90 x 4
4 sec = 360 m
----------------------------------------------------------
Answer: It can travel 360m in 4 seconds.

Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of gallons of water.”How many cups of disinfectant are needed for 20 gallons of water so c is
