Amsar ita ce 4. <eng> Each week she makes $20 * 40 = $800 from her normal hours. For overtime she makes $20 * 1.5 = $30 per hour. Each week she works 52 - 40 = 12 overtime hours per week. She makes a total of 12 * $30 = $360 from overtime every week. This means she makes a total of $800 + $360 = $1160 per week. To reach $4640 she would need to work $4640 / $1160 = 4 weeks. So the answer is 4.
