A meal cost $ 34.50 and there was no tax. If the tip was more than 10 pc but less than 15pc of the price, then the total amount paid should be: Choose one: A) 40 - 42 B) 39 - 41 C) 38 - 40 D) 37 - 39 E) 36 - 37

A meal cost $ 34.50 and there was no tax. If the tip was more than 10 pc but less than 15pc of the price, then the total amount paid should be:
{ "A": "40 - 42", "B": "39 - 41", "C": "38 - 40", "D": "37 - 39", "E": "36 - 37" }
add(multiply(34.5, divide(15, const_100)), 34.5)
divide(n2,const_100)|multiply(n0,#0)|add(n0,#1)
10 % ( 34.5 ) = 3.45 15 % ( 34.5 ) = 5.175 total amount could have been 34.5 + 3.45 and 34.5 + 5.175 = > could have been between 37.95 and 39.675 = > approximately between 38 and 40 answer is c .
