Answer: $391.50</h3>
Work Shown:
1.45*270 = 391.50
The multiplier 1.45 represents a 45% increase
Think of it as 1.45 = 1+0.45 = 100% + 45%
Well if every red marbles is 19, and the rest are black, we need to subtract 120-19. And that equals 101
There are four different choices. Now we have to find which choice best expresses the inequality 1.25x-6.50>50
1.25x has positive sign so any statement that indicates earning like sells at the rate of 1.25 will match with expression 1.25x.
Now -6.50 has negative sign that means this quantity must be subtracted or represents loss of any kind.
Keeping above sign in mind and reading the given statementns, we see that only choice "a" first the given inequality.
Hence final answer is a).
