Answer:
Gabriel sold 31 vacuums.
Step-by-step explanation:
S = 300 + 45v
1695 = 300 + 45v
1395 = 45v
v = 31
This is completely wrong for logical and mathematical reasons, but for the sake of time I will go over the mathematical reason.
Because all percentages are out of 100, nothing can physically be over 100%, though it is used frequently in hyperbolic sentences and exaggerated statements.
Hope I helped and good luck!
Log 10 100 =2
Basically, we have to know how to solve for x in this equation:
10^x = 100
For log3 = 9 we have to solve for x in this equation:
3^x = 9
Therefore, x = 2
420/3 = 140 rubies
Since they use 20 rubies you would do the total amount of rubies by 20.
140/20 = 7
