Answer: Choice C) $3.9098 \times 10^8$

=========================================

Work Shown:

$4.8388 \times 10^8 - 9.29 \times 10^7\\\\4.8388 \times 10^8 - \left(0.929\times10^{1}\right) \times 10^7\\\\4.8388 \times 10^8 - 0.929\times10^{1+7}\\\\4.8388 \times 10^8 - 0.929\times10^8\\\\\left(4.8388-0.929\right) \times 10^8\\\\3.9098 \times 10^8$

-----------------

Side notes:

• $4.8388 \times 10^8 = 483,880,000$ = almost close to 484 million
• $9.29 \times 10^7 = 92,900,000$ = close to 93 million
• $3.9098 \times 10^8 = 390,980,000$ = just a bit under 391 million
