What can you do when the unit prices for two comparable items are listed using different units of measure?
a.
the secondary units don’t affect the cost. as long as both prices are in dollars or cents, you can compare the two.
b.
the unit prices are based on the cost of the whole package, so divide each base cost by each unit price to get comparable units.
c.
use conversion rates to change one unit into the other unit, so that both prices are listed using like units.
d.
unit prices are ratios, so you can add the two prices together and divide by the smaller unit price to get a usable number.

(2) it also kept predators away, allowing early humans to sleep securely. (3) fire, in fact, has been a significant factor in human development and progress in many ways. (4) other obvious benefits of fire are its uses in cooking and in hunting. (5) probably even more important, however, is that learning to control fire allowed people to change the very rhythm of their lives. (6) before fire, the human daily cycle coincided with the rising and setting of the sun. (7) with fire, though, humans gained time to think and talk about the day’s events and to prepare strategies for coping with tomorrow. the sentence that expresses the main idea is: (type the number of the sentence. then click “go.”)
