Jason and Jared have a lawn-mowing service. They charge $20 per hour. One lawn was 150 ft. by 100 ft. and it took 11⁄2 hours to mow. They charged $30. How much should they charge for a similar lawn that is 300 ft. by 200 ft.?

a and b are equal

step-by-step explanation:

one that is bigger than 3 1/2

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce
