Step-by-step explanation:
1. 'x' is the total no. of students and 'y' is no. of 6th graders.
1/3 of the total students are 6th graders.
So the equation will be
1/3 × x = y
x/3 = y
2. If x = 90
y = 90/3
y = 30
3. If x = 27,
y = 27/3
y = 9
4. If y = 42
x/3 = 42
x = 42 x 3
x = 126

Answer:
$500
Step-by-step explanatioThe numberber of years driven is the first and second year
= 2
Miles driven
First year= 15,500
Second year= 14,500
Therefore the cost of depreciation can be calculated as follows
15,500-14,500/2
= 1000/2
= 500
Hence the cost of depreciation is $500
