Answer:
the amount the stock changed over the day = $29
Step-by-step explanation:
The stock cost $122 at the start of the day . At the end of the day it cost $93. The amount the stock value changed can be calculated below.
The initial amount of the stock that days was $122 but at the end of the day it changes to $93. This means the stock cost decreases over the day.
Initial cost of stock at the day = $122
Final cost at the end of the day = $93
the amount the stock changes over the day = initial cost of stock at the day - final cost at the end of the day.
the amount the stock changes over the day = 122 - 93
the amount the stock changed over the day = $29
Generally, the stock decreased over the day.
Jack can swim 12 laps in 28 minutes. 28 minutes is 4 times greater than the time it took him to swim 3 laps. With 28 minutes he should therefore be able to swim 4 times as many laps. 3 times 4 equals 12
Subtract 5x from both sides
0=-30x
Divide both sides by -30
0=x
Final answer: x=0
