Question

Last year, a large trucking company delivered 5.5 × 10^5 tons of goods with an average value of $23,000 per ton. What was the total value of the goods delivered? Write the answer in scientific notation.

Answer 1

`\$1.3\ *\ 10^(10)`

Explanation:

total value = tons of goods * value per ton

So,

`= (5.5*10^5)\ *\ \$23,000 \\= 5.5\ *$ \ 23,000\ *$\ 10^5\\= \$126,500\ *$\ 10^5\\ =\$1.256\ *$\ 10^5\ *$\ 10^5\\=\$1.265\ *$\ 10^(5+5)\\\\Rounding\ off,\ we\ get,\\=\$1.3\ *\ 10^(10)`
