123000 batches = £7380

1200 batches = £3780

Calculate the difference between the two.

1800 batches = £3600

Divide 3600/1800 to find out what one batch with cost... 1 batch = £2.

Put that £2 back into either of your original equations

3000 * £2 + fixed cost = £7380

fixed cost = 7380-6000= £1380

If you've done your maths right then your numbers will work in the other equation as well (1200 * £2 + 1380 = £3780)
