Question

An automobile company sold 2.3 million new cars in a year. If the average price per car was $21,000, how much money did the company make that year? Write your answer in scientific notation.

Answer 1

4.83x10¹⁰

steps

2.3 million = 2 300 000 =

2.3x10⁶

exponent of 10 is 6 because it's 6 spots after the first number

times 21 000 = 2.1×10⁴

exponent of 10 is 4 because it's 4 spots after the first number

2.3 times 2.1 = 4.83

10⁶ times 10⁴ = you add the exponents when you multiply = 10¹⁰

4.83x10¹⁰
