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
$0.42\times 10^{6}=4.2\times 10^{- 1}\times10^{6}=4.2\times 10^{5}$
