Jemma sold twice as many frames as Dorothy, meaning Dorothy sold 400 / 2 = 200 frames. If Dorothy sold her glasses frames at half the price that Jemma sold hers, then it means she sold her glasses frames at $5 / 2 = $2.5 per glasses frame. In total, Dorothy made $2.5 * 200 = $500 from the sale of her glasses frames. Together, they made $2000 + $500 = $2500 from the sale of the glasses frames.
