The question asks "By what percentage did Umaima's bank account INCREASE over the past day?" But since Umaima's bank account dropped from $80 to $66 the percent increase should be negative. It would be clearer if the question asked "By what percentage did Umaima's bank account CHANGE over the past day?" or if the answer was a negative percentage.
