percent change = ((new amount) - (original amount))/(original amount) × 100%

... = ($762 - 289)/($289) × 100%

... = (473/289) × 100% ≈ 164%

This number is positive, so represents an increase. The appropriate choice is

... b. 164%; I

After you find the difference of 473, you can compare it to 289. The ratio is about 480/300 = 1.6, close enough to help you choose 164% instead of 473%. You know it is an increase because 762 > 289.
