the answer is 104.4 because 38+65 is 103. then you add the decimal part of the equation which is 37. If you are rounding to the nearest tenth it would be 104.4
38.94 rounds up to 40 as it is more than half-way between 30 & 40. 65.43 rounds up to 70. even though 65 is half-way, .43 makes it closer to 70 than 60.
