Q. In 2018, a new record was set for the most expensive car ever sold at auction. The car, a 1962 Ferrari, sold for 48,000,000$. What is the approximate price of the Ferrari, written in scientific notation?Choices:(A) 5×10−6 dollars(B) 5×10−7 dollars(C) 5×106 dollars(D) 5×107 dollars
Write Price in Standard Form: First, let's write the price of the Ferrari in standard form: $48,000,000.
Convert to Scientific Notation: Now, we convert this number into scientific notation by moving the decimal point to the left until we have a number between 1 and 10. We count the number of places we move the decimal point to determine the exponent on 10.
Determine Exponent on 10: Moving the decimal point 7 places to the left gives us 4.8. To make it a number between 1 and 10, we need to multiply 4.8 by 107.
Round to Nearest Whole Number: Since the question asks for an approximate price, we round 4.8 to the nearest whole number, which is 5. So, the scientific notation of $48,000,000 is approximately 5×107 dollars.
