2. Decide which estimate is closest to the actual answer. Explain your reasoning.

(a) A store bought 35 lb of produce. If the store spent $100.80, about how much does the produce cost per pound in dollars? 0.03, 0.3, 3, 30
(b) A 6-pack of juice boxes contains 49.2 oz of juice in total. About how many ounces of juice does each juice box contain? 0.8, 8, 80, 800
(c) In 20 L of air, there is about 0.78 L of carbon dioxide. About how many liters of carbon dioxide are there in 1 L of air? 0.04, 0.4, 4, 40 Answer:

Answer 1

Question A
take $100.80 divide it by 35 which would equal 2.88
so round that up for 3.0 for the closest answer

Question B
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0

Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L
