32.01 - 27.97 = 4.04 seconds greater
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
Poster standard dimension: 8.5 inches by 11 inches
Both length and width of the poster may vary 1/20%
∴ length and width may vary 1/20 % = 0.05% = 0.0005
∵ Area = Width * Length
∴ Area = 8.5 * 11 = 93.5 in²
Smallest acceptable area for one poster:
Width: 8.5 * (1 - 0.0005) = 8.49575 in.
Length: 11 * (1 - 0.0005) = 10.9945 in.
∴ The smallest area = 8.49575 * 10.9945 = 93.4065 ≈ 93.407 in².
