Answer:
[tex]75^{\circ}\text{F}[/tex]
Step-by-step 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.
[tex]90-15=75^{\circ}\text{F}[/tex]
Today's temperature is [tex]75^{\circ}\text{F}[/tex]
