Astore sells batteries in packets of 6 or 10. it has a stock of 25 packets containing a total of 186 batteries. how many of these are 10-battery packets?

The answer is: There are 9 packets of 10-battery packets.

Why?

Let's make the calculations:

Let y b the 6-battery packet and z be the 10-battery packet.

We must construct the following to equations using the statement information: There is a stock of 25 packets and there is a total of 186 batteries formed by 6-battery packets and 10-battery packers

So, the first equation will be:

The second equation will be:

From the first equation we have:

Substituting y in the second equation we have:

So, there are 9 packets of 10-battery packets.

By substituting z in the first equation we will know the number of 6-battery packets in stock

So, there are 16 packets of 6-battery packets.
