Question

A store sold 32 pairs of jeans for a total of $1050. Brand A sold for $30 per pair and Brand B sold for $35 per pair. How many of brand A were sold?

Answer 1

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
