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. <ibo> Kwa izu ọ na-akpata $20 * 40 = $800 site n'awa ndị ọ na-arụbu ọrụ. N'ihi ịrụ ọrụ oge nile, ọ na-akpata $20 * 1.5 = $30 kwa awa. Kwa izu ọ na-arụ ọrụ 52 - 40 = awa 12 n'izu.
