Question

The temperature in Jamestown and Cooperville was the same at 1:00 PM. By 2:00 PM, the temperature in Jonesstown dropped 10°, and the temperature in Cooperville dropped 6°. By 3:00 PM, the temperature in Jamestown dropped eight more degrees, and the temperature in Cooperville dropped 2 more degrees.

Write and evaluate a sum to model the change in temperature in Jamestown since 1:00 PM.

Answer 1

To model the change in temperature in Jamestown since 1:00 PM, use the sum: T0 - 10 - 8.

Step-by-step explanation:

To model the change in temperature in Jamestown since 1:00 PM, we can write a sum. Let's start with the initial temperature at 1:00 PM, which was the same as in Cooperville. Let's call it T0. Then, at 2:00 PM, the temperature in Jamestown dropped 10° and at 3:00 PM, it dropped another 8°. So the change in temperature in Jamestown since 1:00 PM can be represented by the sum: T0 - 10 - 8. To evaluate the sum, you need to know the initial temperature at 1:00 PM in both Jamestown and Cooperville.
