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

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