Problema Solution
You have $50 on hand and need to buy gas. How many gallons of gas can you buy for 3.98 a gallon?
Answer provided by our tutors
let 'x' be the number of gallons you can buy with $50 where x is integer thus
x*3.98 <= 50 divide both sides by 3.98
x <= 12.5628
since x is integer the biggest integer smaller then 12.5628 is 12
With $50 you can buy 12 gallons of gas.
