If the price of a stock goes from $4.25 per share to $6.50 per share, by what percent has the
value of the stock increased? round to the nearest whole percent.

53% increase

Work Shown:

A = old value = 4.25

B = new value = 6.50

C = percent change

C = 100*(B-A)/A

C = 100*(6.50 - 4.25)/4.25

C = 52.94%

C = 53%

notes:

The positive C value indicates we have a percent increase. If C was negative, then we'd have a percent decrease.

The formula shown above for C is basically having us compute the difference in price (B-A) and then we divide that difference over the original price A. This computes the decimal form of the answer. The "100*" tacked out front will convert from decimal to percent form.

If you took 52.94% of the original price 4.25, then you would get 0.5294*4.25 = 2.24995 which rounds to 2.25; this is the amount the price increases so we add this to 4.25 and we get 4.25+2.25 = 6.50 which is the new share price.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
