This question is the application of differential eqns in order to derive a model for the temperature dependence with time. Actually, a general equation has already been derived for this type of cases. This equation is known as the Newton's Law of Cooling. The equation is
(T - Ts) / (To -Ts) = e^(-kt)
where T is the the temperature at any time t
Ts is the surrounding temperature
To is the initial temperature
k is the constant
t is the time
several assumptions have been made to arrive at this form, i suggest you trace the derivation of the general formula.
First we need to look for k using the initial conditions that is @t = 1.5 min, T = 50 F
substituting we get a k = 0.2703
therefore @ t = 1 min, T = 55.79 F
@ T = 15 F the time required is 9.193 min.

Answer:
Sales goal, S = Q. 10,000
Step-by-step explanation:
- Let the daily sales goal be S.
<u>Given the following data;</u>
- Amount sold = Q. 2,000.00
- Percentage of the sales goal = 20%
To find his daily sales goal;
Dividing both sides by 0.2, we have;
<em>Sales goal, S = Q. 10,000</em>
