Problema Solution
Shane returned from a trip to Las Vegas with $336.00, which was 40% more money than he had at the beginning of the trip. How much money did Shane have at the beginning of his trip?
Answer provided by our tutors
let 'm' represent the amount of money Shane had when he began his trip, then 'm + 0.4m' represents a 40% increase in his money:
336 = m + 0.4m
solving for 'm' we have m=257.14
Shane had $257.14 when he began his trip
