Answer:
There are 14 pairs of Brand A sold.
Step-by-step explanation:
In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:
A + B = 32
And you can set up one for the amount made:
30A + 35B = 1090
Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.
-35A - 35B = -1120
30A + 35B = 1050
----------------------------
-5A = -70
A = 14
