Question

Jabari owns 100 shares of Stock A and 45 shares of Stock B. For the past month, his stocks have been fluctuating inversely each week. Stock A decreased by m cents per share and Stock B increased by n cents per share. Which equation can be used to find the total change in value of Jabari's shares?

PLEASE HELP MEEEEEE.

Answer 1

0.45 because Stock A = 100 and Stock B = 45

Since his stocks inversely decreased you have to do.
Stock A = m cents / share
Stock B = n cents * share

So the equation is
= 100 (0.01m) + 45 (0.01n)
= m + 0.45n

Answer 2

equation for change in Jabari's shares value = 0.45n - m

Explanation:

Jabari owns 100 shares of stock A and 45 shares of stock B.

Past month, stock A decreased by m% per share so total decrease in value of 100 shares = 100×(-0.01m)

Stock B increased by n% per share so increase in value of 45 shares = 45×(0.01n)

Total change in value = 45(0.01n) + 100(-0.01m)

= 0.45n - m

Therefore, change in value of Jabari's shares = 0.45n - m will be the equation.
