Answer 1

To find out how much the price is changing per day, we need to divide the total decrease in price by the number of days over which the decrease occurred.

The total decrease is $21.50 over 5 days.

Now, we calculate the daily change:

\[ \text{Daily change} = \frac{\text{Total decrease}}{\text{Number of days}} = \frac{21.50}{5} = 4.30 \]

Since the price decreased, the daily change will be negative:

\[ \text{Daily change} = -4.30 \]

Thus, the price is changing per day by -$4.30.

The correct response is:

−$4.30
