Answer:
1.71 × 10^8 gallons
Step-by-step explanation:
1.9 × 10^7 = 19,000,000
19,000,000 × 9 = 171,000,000
171,000,000 in scientific notation is 1.71 × 10^8
To find the total amount Leo should give, simply find the 20% of his bill then add it.
Total cost = $45.90 + ($45.90 × 0.20)
Total cost = $45.90 + $9.18
Total cost = $55.08
Therefore, Leo should give $55.08 in total to leave a 20% tip.
To find the contribution of each man (this is a sexist problem as women could work as well, but that’s besides the point) take 5/2 and then multiply that value by 20 and you’ll find it takes 50 hours for two men to do it.
