The cost of the family’s cell phone plan rose from $130 to $194 when they added a phone for their daughter. What was the percent of increase?

Step-by-step explanation:

Step one:

initial price=$130

final price=$194

Step two:

we know that the percent increase is given as

% increase= final-initial/initial

substituting we have

% increase= 194-130/130*100

% increase= 64/130*100

% increase= 0.49*100

% increase= 0.49*100= 49%

therefore the percent increase is 49%

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
