Answer:
He must sell 8 cards to reach the minimum goal.
Step-by-step explanation:
Giving the following information: 
He wants to earn more than $50 at the fair.
He sells his cards for $2 and he has already earned $36.
<u>First, we need to calculate the money required to reach the minimum goal:</u>
51 - 36= $15
<u>Now, we write the inequality:</u>
2*x >15
x= number of cards sold.
x>15/2
x> 7.5
He must sell 8 cards to reach the minimum goal.

Answer:  1</h3>
Explanation:
The jump from 2 to 2&1/2 is an increase of 1/2
2 + 1/2 = 2 & 1/2
The jump from 2 & 1/2 to 1 & 1/2 is a decrease of 1
(2 & 1/2) - 1 = (2 - 1) & 1/2 = 1 & 1/2
The jump from 1 & 1/2 to 2 is an increase of 1/2
(1 & 1/2) + 1/2 = 1 + (1/2 + 1/2) = 1 + 1 = 2
The pattern seems to be "add 1/2, subtract 1". Assuming this is the case, we would then subtract 1 from the last term we got (2) to get 2-1 = 1
 
        
        
        
To find the circumference, you multiply the diameter by pi (3.14).
94 * 3.14 = 295.16
