The price of a gallon of milk went from $2.70 to $3.50 in four years. Find the rate of change of the price of the milk

The rate of change in price is

$0.2 per year

Step-by-step explanation:

This problem bothers on rates

Given data

Initial price of milk = $2.7

Final price of milk = $3. 5

Time duration = 4 years

Hence the rate of the change of price can be estimated as follows

= Δ in price/Δin time

= (Final price - initial price) / 4

=3.5-2.7/4

=0.8/4

=$0.2 per year

milk went up to a $1.20
