6 × 10^-10
Hope this helps
Answer:
No solutions.
Step-by-step explanation:
22 does not equal 81, so therefore no solutions.
Multiplying 0.7 by the original price will work...
If you divide the cost by 100, subtract 30 from 100, you will be left with 70% times the 1/100
70% is also expressed as 0.7, since 7/10=70/100
Hope this helps!
