Jabari owns 100 shares of Stock A and 45 shares of Stock B For the past month, his stocks have been fluctuating inversely. 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 per month?

Answer is

(100*-m)+(45*n)

Step-by-step explanation: because stock  decreases per sock so you're going to multiply 100 times -m because it is decreasing so it will be negative

Then it will be 45*n because it increases per number of stocks so you multiply 45 which is the number of stocks times n

Step-by-step explanation:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
