Answer: 
So, there are 3 cards in total, which means your pobability of picking one card out of the 3 cards is %33.33. So the probability of picking a 7 is 1/3. Because the other two numbers are greater than 7, and you already picked 7 so you cannot pick it again, the probabitily of pick a number greater than 7 is %100, or 3/3.
I hope that answers your question! :)
 
        
             
        
        
        
The inequality to describe the situation is; 2a + 1b <= 18
Since according to the question;
- Tony has $18 to buy apples and bananas for a fruit salad.
 
- Apples cost $2 per pound and bananas cost $1 per pound.
 
- Let the number of apples bought be; a
 
- Let the number of bananas bought be; b
 
Therefore, the inequality to describe the situation is;
This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.
Additionally, Two possible combinations of pounds and apples that Tony can buy are;
- Tony buys 9 apples and no banana
 
- Tony buys 18 bananas and no apple.

Answer: the commission received by the salesperson is $576.9225
Step-by-step explanation:
Let x represent the auction price
At the dealership, a sales person sold the boat for 30% more than the auction price. It means that the amount for which he sold the boat is
x + (30/100 × x)
= x + 0.3x = 1.3x
If the dealer paid $10,000 for a boat at an auction, it means that 
1.3x = 10000
x = 10000/1.3
x = 7692.31
The difference between the auction price and the dealer price is 
10000 - 7692.31 =$2307.69
The sales person received a commission of 25% of the difference between the auction price and the dealer price. It means that the commission received by the salesperson is 
25/100 × 2307.69 = $576.9225
