1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.
3.) if x is gallons of gas used, y is distance driven. the equation that describes this relationship is y=20x.

Answer: 0.10(n)=25+0.05(n-200)
Explanation:
The number of business cards are n
Plan A: No initial fee and $0.10 for each business card
Plan B: $25 for the first 200 business cards
and surplus of $0.05 for each additional card
As n is total business cards
so from plan A equation is
0.10(n)
from plan B
25 + 0.05(n-200) if n > 200
Now as a whole the equation for no of business cards would be
0.10(n)=25+0.05(n-200)
