It was -8 degrees Fahrenheit in Denver and -15 degrees Fahrenheit in New York. Which city was colder

The Answer is New York.

Step-by-step explanation:

-15 is less than -8

-8, -9, -10, -11, -12, -13, -14, -15

We can set up equations to help us out

8x + 15= y

10x=y

If she has a 3 hour job, we can plug 3 in for x to find out which is better

8(3) + 15=y
24 + 15= y
39=y for a landscaping service

10(3)=y
30=y for a neighbors help

Since it will cost her 9 dollars less, she should go with the neighbor
