Answer :

To determine how much the price of one share of Acme Company changed in total after 4 days, follow these steps:

1. Identify the daily decline in the price of the share:
- The price of the share declines by [tex]$5 each day. 2. Determine the number of days over which this decline occurs: - The decline happens over 4 days. 3. To find the total change in the price over these 4 days, multiply the daily decline by the number of days: - Daily decline: $[/tex]5
- Number of days: 4

4. Calculate the total decline:
- [tex]\[ \text{Total decline} = 5 \, (\text{dollars/day}) \times 4 \, (\text{days}) \][/tex]

5. The product of this calculation gives the total price change:
- [tex]\[ \text{Total decline} = 20 \, \text{dollars} \][/tex]

Therefore, the price of one share changed by a total of $20 after the 4 days.
