Question

The price of apples went from $ 1.99 per lb to $ 3.19 lb in four years. find the rate of change of the price of apples.

Answer 1

The rate of change of the price of apples can be calculated by finding the difference in price and dividing it by the number of years. In this case, the rate of change is $0.30 per year.

Step-by-step explanation:

The rate of change of the price of apples can be calculated by finding the difference in price and dividing it by the number of years. In this case, the price of apples increased from $1.99 per lb to $3.19 per lb in four years. To find the rate of change, subtract the initial price from the final price and divide it by the number of years:

Rate of change = (Final price - Initial price) / Number of years

So, the rate of change of the price of apples is:

Rate of change = ($3.19 - $1.99) / 4 = $1.20 / 4 = $0.30 per year

Answer 2

Do 3.19-1.99. U will get 1.2. Set a proportion of 1.2/1.99= x/100. Solve for x and get 60.3015 which will round to 60.3. So the percent of increase is 60.3 percent
