Question

the table gives the temperature (in °f) in five cities at 6 a.m. on the same day. use the table to answer the questions.

city	temperature (°f)
atlanta	62
winnipeg	-17
chicago	-2
st. louis	49

(a) by noon, the temperature in chicago had risen by 9 °f. what was the temperature there at noon?

(b) how much higher was the 6 a.m. temperature in winnipeg than in juneau?

Explanation:

Part (a)

Step1: Identify Chicago's 6 a.m. temp

From the table, Chicago's 6 a.m. temperature is \(-2^\circ\text{F}\).

Step2: Calculate noon temperature

The temperature rose by \(9^\circ\text{F}\), so we add: \(-2 + 9 = 7\).

Step1: Identify 6 a.m. temps

Winnipeg's 6 a.m. temp: \(-17^\circ\text{F}\), Juneau's 6 a.m. temp: \(-28^\circ\text{F}\).

Step2: Find the difference

Subtract Juneau's temp from Winnipeg's: \(-17 - (-28) = -17 + 28 = 11\).

Answer:

The temperature in Chicago at noon was \(7^\circ\text{F}\).
