2 a + b = 15.7
Since the sides are equal length, the equation is:
2 · 6.3 + b = 15.7
We can solve it:
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
Answer: Option 'B' is correct.
Step-by-step explanation:
Number of pounds of candy = 30

Total amount would be

Let the number of pound that sold at $1.50 per pound be 'x'.
Let the number of pound that sold at 90 cents per pound be '30-x.
According to question, we get that

Hence, there are 10 pounds of chocolates worth $1.50 per pound.
Therefore, Option 'B' is correct.
