Answer:
1.848 × 10^-2
Step-by-step explanation:
0.006 = 6 × 10^-3
3.08 = 3.08 × 10^0 (10^0 is equal to 1)
(6 × 10^-3) × (3.08 × 10^0) = 18.48 × 10^-3 = 1.848 × 10^-2
Answer: $30,000
Step-by-step explanation:
If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.
This way X . 90% = 27,000
X . 0.90 = 27,000
X = 27,000/0.9
X = 30,000
Counter-proof: 30,000 . 10% = 30,000 . 0.10 = 3,000
30,000 - 3,000 = 27,000
