Answer:
$150
Step-by-step explanation:
First use a proportion to find the answer:
40/100=60/x
Now we solve for x
60*100=6,000
6,000 divided by 40= 150
x=150
Therefore the answer is $150
Let number of senators = x, then:-
number of representatives = 5x - 25 so
x + 5x - 25 = 515
6x = 540
x = 90
number of reps = 515 - 90 = 425
so there are 90 senators and 425 representatives.
Supplementary would be like 6&7 or 2&3 and vertical would be like 6&8 or 7&5
