Answer:
D) 6.79 x 10^7
Step-by-step explanation:
Company D has the greatest revenue because it is multiplying by 10 to the power of 7 which is the same as multiplying by 10 seven times. The least revenue is company C because it is only multiplying by 10 to the power of 4 which is the same as multiplying by 10 4 times.
6.8 x 10^7 = 68,000,000
9 x 10^4 = 90,000
68,000,000 - 90,000 = 67,910,000.
Convert this back into standard form to get 6.79 x 10^7
