19 last year, company t sold 2.8×10^6 vehicles, and company h sold 15 percent of the number of vehicles that company t sold. how many vehicles did company h sell last year? show your work on the scratchpad, and give your answer in scientific notation.
Answer
# Answer:
$4.2\times 10^{5}$
# Explanation:
## Step1: Convert 15% to decimal
$15\%=0.15$
## Step2: Calculate number of vehicles Company H sold
$0.15\times(2.8\times 10^{6})=(0.15\times2.8)\times 10^{6}$
$0.15\times2.8 = 0.42$
So, $0.42\times 10^{6}$
## Step3: Adjust to scientific - notation
$0.42\times 10^{6}=4.2\times 10^{- 1}\times10^{6}=4.2\times 10^{5}$
