The missing equation is:
You are given:
- Ta = the temperature surrounding the object = 73ºF
- T₀ = the initial temperature of the object = 204ºF
- t = 2.5 min
- T after 2.5 min = 180ºF
Question 1: Find the the value of k.

You would have to subtract x on both sides and then divide 2 on both sides as well. whatever you do on one side, you have to do it on the other side. Hope this helps. After you redo all the equations, you graph them. If you need anymore help , let me know!
So 2 weeks mean
250x 2= 500
Then .50 per mile so 500 miles mean
.50 x 500= 250
In total it will be
