ASVAB Practice Test

Jerry walked the dog for a total of 50 minutes or 0.83 hours (730 - 6:40 = 0:50 or 50 minutes). At a rate of $6 per hour, he would earn $4.98 (0.83 x $6 = $4.98). $4.50 is the closest answer option to $4.98, making it the correct answer. The other answer options are incorrect because they are either too low or too high. For example, B, $5.00, is too high as it assumes that Jerry walked the dog for exactly one hour, which he did not. Option D, $6.00, is too high as it assumes that Jerry walked the dog for longer than the actual time he spent. Option C, $5.50, is closer to the correct answer but still too high as it assumes that Jerry walked the dog for 55 minutes, which is longer than the actual time.
