If Simone has 20 bills, then:
1/5 of 20 = 4 [hundreds]
1/4 of 20 = 5 [fifites]
1/10 of 20 = 2 [$20s]
4 * 100 + 5 * 50 + 2 * 20 = 400 + 250 + 40 = 690 [out of $780]
4 + 5 + 2 = 11 [out of 20 bills]
So now we can easily find out she had 9 bills of tens - because 20 - 11 = 9 or because (780 - 690) ÷ 10 = 90 ÷ 10 = 9.

Answer:
Total cost to buy required lemons = $ 2.8
Step-by-step explanation:
Selling price of each lemon = $0.35
One 9-inch lemon pie requires 0.5 cup of lemon juice
⇒ Two 9-inch lemon pie will require 2 × 0.5 = 1 cup of lemon juice
In general, One cup contains 16 tablespoons of juice
Now, 2 tablespoons of juice is yielded by one lemon

NOw, Cost of 1 lemon = $0.35
Therefore, Cost of 8 lemons = 8 × 0.35 =$ 2.8
Hence, Total cost to buy required lemons = $ 2.8
