14. A Don’t calculate! Identify what the quantities have in common. Since both
quantities share the product (5 × 6 × 7 ×... 24), you can divide both quantities
by the product of the integers from 5–24, inclusive. After doing so, the real
comparison becomes:
QUANTITY A QUANTITY B
25 1 × 2 × 3 × 4
1 × 2 × 3 × 4 = 24. Thus Quantity A is greater.- B Since the comparison is between a value and a variable, you can work
backward. If x = 7, then x^2 = 49 < 36. Thus to satisfy the given inequality, x
must be less than 7. - A Since the quantities compare a value to an unknown, work backward with
Quantity B. If the selling price of the coat were $240, then the profit on the
coat would be 240 – 200 = 40. Now determine 40 as a percentage of 200.
40
200 × 100 = 20%. Since you know that the profit must be greater than 20%, the
selling price must have been greater than $240.
