Answer 2

Answer: Rate of change of the price of bread is 0.25 or 25%.

Step-by-step explanation:

Since we have given that

Initial price of bread = $1.50 per loaf

After 4 years,

Price of bread becomes = $2.50 per loaf

So, Rate of change of the price of bread is given by

$\dfrac{New-Initial}\text{Number of years}}\\\\=\dfrac{2.50-1.50}{4}\\\\=\dfrac{1}{4}\\\\=0.25\\\\0.25\times 100=25\%$

Hence, Rate of change of the price of bread is 0.25 or 25%.
