Answer: 3.6 feet per year
Pick any column and divide the feet over the years
eg: 7.2/2 = 3.6 (column 1)
You can think of it as the ratio
7.2 feet: 2 years
and then divide both sides by 2 to get "1 year" on the right side
7.2 feet: 2 years
7.2/2 feet: 2/2 years
3.6 feet: 1 year

Answer:
number of cars: x = 30
number of vans: x = 14
Step-by-step explanation:
For 44 cars, the amount they collected would have been 44*5 = 220 dollars, but the total was 262 dollars, which is 42 dollars more.
Each van costs $3 more than each car. $42 "extra", divided by $3 "extra" for each van, means 42/3 = 14 vans. And that leaves 30 cars.
check: 30(5)+14(8) = 150+112 = 262
or, using algebra...
let x = the number of cars
then 44-x = number of vans
