Solution:
Slope = y2 - y1 / x2 -x1
slope = 81 - 111 / $2.00 - $1.25
slope = -30/$0.75
So every $0.75 increase causes a decrease of 30 sales.
So the rise over run or slope of the line is -30/0.75 = -40/1
Start forming the equation:
y = mx + b
y = -40x + b
Substitute one of the points to find the y-intercept:
81 = -40(2) + b
Isolate for the y-intercept:
b = 161
So,
y = -40x + 161
Answer: How is compound interest different from simple interest?
Explanation: Simple interest is interest payment is calculated on only the principal amount; whereas compound interest is interest calculated on both the principal amount and all the previously accumulated interest.

Answer:
The price of the airplane today is $24.15
Explanation:
In this question, we proportionate the items
Since, for the 1983 year, the price is given and the CPI for today and in 1983 is also given.
So, the price of the airplane would be
= CPI today × (Price in 1983 ÷ CPI in 1983)
= $24.15
We divide the 1983 price with the 1983 CPI and then multiply the CPI to get the price for today.
