The price of bread went from $1.75 per loaf when Sally started tracking it to $3.50 per loaf in five years. Find the rate of change of the price of bread.
Responses
$0.35 per year
$0.75 per year
$1.75 per year
$0.25 per year
$0.35 per year.
To find the rate of change, we can use the formula:
Rate of change = (change in price) / (time)
In this case, the change in price is:
$3.50 - $1.75 = $1.75
And the time is 5 years. Substituting these values, we get:
Rate of change = $1.75 / 5 = $0.35 per year
Therefore, the correct response is $0.35 per year.
