Twelve months ago, Donnie bought shares of stock in a Biotechnology Company for $25 per share. If the shares are now selling for $30 per share, what is the percent of increase in the value of the stock?

25%

Step-by-step explanation:

Buying price: $25 per share

Selling price: $30 per share

=> the percent of increase in the value of the stock is calculated as the following formula:

({Selling price - Buying price)/Buying price} *100%

= {($30 - $25)/$25} *100%

= 1/5*100%

= 25%

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
