What is the expected temperature of the soda after an additional 12 minutes?I know the answer is 56.9 because this was on my test. Can someone help me with a formula please?-Are you sure it is 56.9?......
Jodi poured herself a cold drink that had an initial temperature of 39 degrees F and immediately went outside to sunbathe where the temperature was a steady 96 degrees F. After 5 minutes, the temperature of the soda was 45 degrees F. Jodi had to run back into the house to answer the phone. What is the expected temperature of the soda after an additional 12 minutes?

I know the answer is 56.9 because this was on my test. Can someone help me with a formula please?

Are you sure it is 56.9?

I got 59.4:

39 + 5x = 45
5x = 6
x = 1.2

45 + 12x = y
45 + 14.4 = y
y = 59.4
