Let the value of the vehicle be described by the equation
V = a + bx
where x = number of years since purchase
a,b are constants.
When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500
When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000
The equation is
V = 7500 - 1000x
The slope of this equation is the depreciation rate, and it is -$1000 per year.
Answer: $1000 depreciation per year.
Answer: 36

Explanation:
There are 35 girls and 50 boys. Making 35+50 = 85 students total.
Of the 85 students, 42% (see column 1, bottom row) bought their lunch from the cafeteria. So 0.42*85 = 35.7 which rounds to 36
