The answer to the question
Answer:
1900
Step-by-step explanation:
570/12 = The rate at which James earns money, or $47.5
47.5 × 40 = 1900 Because you wan to know the value after 40 days

Answer:
415,000
Step-by-step explanation:
First, find the decimal equivalent of 125%. To do this, divide 125 by 100 or move two decimal places to the right: 125/100 = 1.25
Now multiply the amount of cars sold last year, 332,000, by the percentage decimal, 1.25: 332,000 x 1.25 = 415,000
The car manufacturer sold 415,000 cars this year
