Jeff wants to buy a phone car for long distance call. he can buy a 200 minute card for $10.00 or a 300-minute card for $12.00.which card is better value?
show ur work.

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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
