Hey!
You must divide the amount of money he spent by the amount of money each ticket costs:
32 ÷ 8 = 4
So, Mr. Chen bought 4 tickets.
right 3 units down 5 units

right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.

Then convert the vertex form into standard form for the equation in the choice.

Thus, the answer is B.
35 = 70%
If you divide 35 by 7, you will find what 10% of your maximum bid is.
35/7 = 5
5 = 10%
Multiply your value of 10% by 10 to get 100%.
5*10 = 50
Your maximum bid would be $50. You actually spend $35. To find the amount more you were willing to pay, subtract the two values.
$50-$35 = $15
Answer: You were willing to pay 15 more dollars than you did.
