Answer:
a = 0.3
b = 0.4
c = 40%
d = 15%
Step-by-step explanation:
There are a total of 10 tick marks. So we know that 1 tick mark = 10%
a has 3 tick marks so you can say it's 0.3
b has 4 tick marks so you can say it's 0.4
c also has 4 tick marks, but it's asking for the percentage, so you get 40%
d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%
The change in the stock market from the beginning of the day to the end of the day is 29 3/4
<h3>How to determine the change in the stock market from the beginning of the day to the end of the day?</h3>
The given parameters are:
Beginning = 60 3/4
End = 90 1/2
The change in the stock market from the beginning of the day to the end of the day is calculated as;
Change = End - Beginning
So, we have
Change = 90 1/2 - 60 3/4
Evaluate
Change = 29 3/4
Hence, the change in the stock market from the beginning of the day to the end of the day is 29 3/4
