The monthly cost of downloading songs at b-Tunes is $0.99 per song. I-Music charges a
monthly fee of $10 plus an additional $0.79 per song. How many songs would you have to
download for the two plans to cost the same?

50

Step-by-step explanation:

0.99x = 10 + 0.79x

0.2x = 10

x = 10/0.2 = 50

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.
