Visualize pi/2 as 90° on the unit circle. this has no real component, only imaginary. same for 3pi/2, or -pi/2 as shown in this equation:

She could buy 3 pairs of jeans and 3 sweaters because any more than that she would not have enough for because 3 jeans and 3 sweaters would equal $297
65x3=195

2x² - 15x + 7
(2x - 1)(2x-14)
(2x - 1)(x - 7) x= 1/2 or 7
