A farmer produced 8000 tonnes of grain last year. He plans to increase this by 15% next year. How many tonnes does he think he will produced?

A car costs $11500 new but lost 5% of its value in the first three years. What is worth after 3 years?

1.15 * 8,000

To find out how many tonnes of grain the farmer thinks he will produce next year, you can calculate the increase using the following steps:

1. Start with the current production of grain, which is 8000 tonnes.
2. Calculate the increase by finding 15% of the current production. To do this, multiply 8000 by 0.15. (8000 * 0.15 = 1200)
3. Add the increase to the current production to find the farmer's expected production for next year. The calculation is: 8000 + 1200 = 9200.

Therefore, the farmer expects to produce 9200 tonnes of grain next year.
