The number in question is 7.5
Step-by-step explanation:
15 ÷ 2 = 7.5

Answer:
Part A:
Expression 1: 0.7B
Expression 2: B - 0.3B
Part B:
$504
Step-by-step explanation:
Part A:
Original price: B
B is 100% of the price. The discount is 30%.
100% - 30% = 70%
After the discount, the price is 70% of the original price.
70% of B is the same as 0.7B
Expression 1: 0.7B
Original price: B
Discount: 30% of B
Discounted price = B - 30% of B = B - 0.3B
Expression 2: B - 0.3B
Part B:
Use Expression 1 to calculate the price.
0.7B = 0.7 * $720 = $504
