The real part does not have i as a multiplier. It is 23.3.
The imaginary part* is the coefficient of i: 44.
_____
* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
1 kg = 1000g Total bag weight in grams = 1.8 x 1000 = 1800g total bag weight / golf ball weight = total balls in bag 1800 / 45 = 40 Total balls in bag = 40.
