 
 <translate> The amount that the couple would cover for the hospital bill is $128 / 2 = $64. The couple's total expenses (salary and hospital bill) is $160 + $64 = $224. So each of them should give $224 / 2 = $112 in total. Since the husband paid the entire half of the hospital bill already ($64), he still needs to pay $112 - $64 = $48.
Thus, the answer is 48. <hau> Adadin da ma'auratan za su biya na kuɗin asibiti shi ne dala 128 da rabi = dala 64.
