Jared will be on the phone for 22 minutes.
The mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. Indicators of proportions include "::" and "=".
Given
Let time to be calculated be z
Rate of cost of call = time / cost = x = 15/0.90
Rate of cost of call = time / cost = y = z/1.32
Rate of cost is constant
x = y
According to laws of proportion
15/ 0.90 = z/ 1.32
z = 15/0.90 * 1.32 = 22
Therefore, Jared will be on the phone for 22 minutes.
