Answer:
Hence, making the stock worth when trading ended $157.6
Step-by-step explanation:
Total at the beginning is $156
Step One:
Try to find the equation for when the Stock for a company fell $1.75 per hour for 4 hours, you'll first need to know how much $1.74 per hour for 4 hours is;
1.75(4)=7
Than subract the answer above (7) from the total in the beginning to see exactly how much fell;
156-7=149
Step Two:
Furthermore, it states; "..but then gained back $2.15 per hour for the next 4 hours until the stock market closed..."
so now you need to take the answer from Step One, 149 and add 2.15 for every hour for 4 hours;
149+2.15(4)=157.6
