John earns $200 per project for the first five projects, $250 per project for the next 10 projects, and $350 per project for any additional projects he completes. Identify the amount John will earn for completing 20 projects.

Step-by-step explanation:

John earns $200 per project for the first five projects. It means that the total amount he earned for the first five projects is

He $250 per project for the next 10 projects. It means that the total amount he earned for the next 10 projects is

250 × 10 = $2500

He 350 per project for any additional projects he completes. If he completed a total number of 20 projects, then the number of additional projects that he completed is 20 - 15 = 5. He earned $350 per project for any additional projects he completes. It means that the total amount he earned for the additional 5 projects is

5 × 350 = $1750

Total amount earned for completing 20 projects is

1000 + 2500 + 1750 = $5250
