The correct answer would be A. C = 0.69p. 
This is the correct answer because the total cost of the bananas should equal 0.69 times each pound bought.
Hope this helped!
        
             
        
        
        
1. "Kevin has a 15% off coupon for buying water bottles at Walmart.
One water bottle is usually $2.00. How much did Kevin pay with his coupon?"
2. $1.70.
3. The answer is $1.70, because $2.00 * 0.15 = 30 cents, which is how much the coupon is worth. The sale price is the original amount minus the coupon's monetary value (which is $2.00 - $0.30 = $1.70).
4. I'll leave that part to you lol
        
             
        
        
        
If there are ten black pens, eight blue pens, and twenty pens in total, then there are 2 red pens. This means that the ratio of red to black is 2:10=1:5. Hope this helps!
