6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity
The answer is 3:2. That is the answer.
Answer:19
Step-by-step explanation:
Divide 190 by 10
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.
Answer:
y= -6x - 51
Step-by-step explanation:
5y = -6x - 10
Slope: -6
y = -6/5x - 2
Point: (-10,9)
y-intercept: 9 - (-6)(-10) = 9 -60 = - 51
