Can someone me with this math question ?

1. V = (100-m) + 45×n

Step-by-step explanation:

We are given that,

Total number of shares of stock A = 100

Total number of shares of stock B = 45

Now, it is given the stock A is decreased by m cents per share, which provides that,

So, Number of shares of stock A = 100 - m

Also, the shares of stock B are increased by n cents per share,

i.e. the increase of 1 stock is by n cents, therefore the increase of 45 stocks will be of 45×n cents.

So, Number of shares of stock B = 45×n

Hence, the total change in shares = Number of shares of stock A + Number of shares of stock B = (100 - m) + 45×n.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
