a furniture store owner decided to drop the price of her recliners by 20 % to spur business . by the end of the week she had sold 50 % more recliners . what is the percentage increase of the gross ?
n0 = 20.0
n1 = 50.0
t0 = n1 / 100.0
t1 = n0 / 100.0
t2 = t0 + 1.0
t3 = 1.0 - t1
t4 = t2 * t3
t5 = t4 * 100.0
answer = t5 - 100.0
