Question

The average temperature in Lincoln in July is 85 degrees. Last Wednesday, it was 90 degrees. Today it was 15 degrees cooler than last Wednesday. What was the temperature today?

Answer 1

`75^(\circ)\text{F}`

Explanation:

Last Wednesday it was 90 degrees Fahrenheit.

Today it is 15 degrees Fahrenheit colder than it was last Wednesday.

So, today's temperature will be the difference of the temperatures of last Wednesday's and today's temperature. We have to find the difference as it is colder today means it is a lower temperature than last Wednesday's.

`90-15=75^(\circ)\text{F}`

Today's temperature is
`75^(\circ)\text{F}`
