Step-by-step explanation:
x = amount of shares for $6.25
y = account of shares for $6.50
x + y = 500
x×6.25 + y×6.5 = 3218.75
x = 500 - y
(500 - y)×6.25 + y×6.5 = 3218.75
3125 - y×6.25 + y×6.5 = 3218.75
0.25×y = 93.75
y = 375
x = 500 - 375 = 125
so, he bought
375 shares of $6.50
125 shares of $6.25
Based on the data given on the number pattern, 4 + 5 = 180
<h3>Number pattern</h3>
7 + 9 = 254016
3 + 7 = 7779240
5 + 8 = 2496000
7 + 9 = (7 × 9)^|7-9| × (7 + 9) × |7 - 9)
= 69² × 16 × 2
= 4761 × 16 × 2
= 254,016
3 + 7 = (3×7)^|3-7| × (3+7) × |3-7|
= 21⁴ × 10 × 4
= 194,481 × 10 × 4
= 7,779,240
So,
4 + 5 = (4×5)^|4-5| × (4+5) × |4-5|
= 20¹ × 9 × 1
4 + 5 = 180
