Answer: $70400
Step-by-step explanation:
Attached is the question:
Based on the information given in the question:
Value of Stock X = 5000 × $4.30 = $21500
Value of Stock Y = 2000 × $3.20 = $6400
Value of Stock Z = 8000 × $4.90 = $39200
Total Stock Value = $67100.
Since there's a 4.9% increase in value of index, the value of the index at end of the day will be:
= $67100 × (100% + 4.9%)
= $67100 × 104.9%
= $67100 × 1.049 =
= $70388
= $70400 approximately
First, distribute the parenthesis:
(2x - 4) (4x - 5) = 8x - 20
\___\_/___/

2x * 4x, 4 * 5
Then you add 20 to both sides
8x - 20 = 0
+20 +20
8x = 20
Then you divide both sides by 8
x = 2.5
I think I did that right... I don't quite remember what a solution set is
(2x - 4) (4x - 5) = 8x - 20
\___\_/___/

2x * 4x, 4 * 5
Then you add 20 to both sides
8x - 20 = 0
+20 +20
8x = 20
Then you divide both sides by 8
x = 2.5
