The price of a sweater went up 20% since last year.If last year's price was x what is this year's price in terms of x?
please explain how you got 1.2x
1.2x
The price this year is 100% plus 20% higher than last year.
120% = 1.2
Well, well, well, looks like that sweater's feeling extra fancy this year! If the price went up by 20% since last year, we can calculate this year's price by adding 20% of x to x. So, this year's price is x + 0.2x, or simply 1.2x. Voila, you've got your answer! Keep those stylish sweaters warm!
To find this year's price in terms of x, we first need to calculate the 20% increase from last year's price.
Let's start by calculating the amount of the 20% increase. The increase is 20% of x, which can be expressed as:
Increase = 20% * x
To calculate the 20% of x, we can convert 20% to a decimal by dividing it by 100:
Increase = (20/100) * x
Simplifying the equation:
Increase = 0.2 * x
So, the increase in the price of the sweater since last year is 0.2x.
To find this year's price, we need to add the increase to last year's price:
This year's price = Last year's price + Increase
= x + 0.2x
= 1.2x
Therefore, this year's price in terms of x is 1.2x.
