Answer:
8 trips
Explanation:
Rounding to the largest place value of 7,460 is 7,000
Considering 7 * 5 = 35, and 35 * 2 = 70 (you can scale up the problem to the thousands such as 70 * 50 = 3,500, etc) so since 7 * 10,000 is 70,000 we can estimate that the plane driver can take about 8 trips (70,000 - 7,000, or 1 trip then we account for the extra 460 gallons for each trip then we just take off one more trip.)
