To find the temperature at which the ice cream shop would have a positive profit, we need to solve for t in the equation c = 17.6t - 721.6 when c is greater than zero.
Given the equation: c = 17.6t - 721.6
Setting c > 0:
0 < 17.6t - 721.6
17.6t > 721.6
t > 41
Therefore, a temperature above 41 degrees Fahrenheit would make the ice cream shop have a positive profit.
An ice cream shop was doing research on its sales. The results showed that the relationship between the average daily temperature in Fahrenheit, t, and the daily ice cream profit in dollars, c, could be modeled by the
equation c = 17.6t - 721.6.
According to the model, which of the following temperatures to the nearest tenth of a degree would make the ice cream shop have a positive profit?
