Question

Gabe is analyzing the plane ticket prices over the years. Comparing the cost of a plane ticket this year to last year, ticket prices are 12% higer than they were last year. Create an expression that represents the difference between this year and last year

Answer 1

The difference in prices is 0.12x where x is the last year’s price

Explanation:

Here, we want to create an expression

Let the price last year be x

12% more this year mean;

x + 12% of x

= x + 0.12x = 1.12x

So the difference between this year and last year will be;

1.12x - x = 0.12x
