X=127, I like using Desmos online graphing calculator for these problems.
Yes. It is reasonable to say that 24 more families chose Hawaii over Florida.
- To say that 24 more families chose Hawaii over Florida implies that the number of families that chose Hawaii is greater than the families that chose Florida by 24.
- For example, if 30 families chose Florida, then the number of families that chose Hawaii will be 54 (30 + 24).
Thus, it is very reasonable to conclude from the survey that 24 more families chose Hawaii over Florida.

S+D+K=155
K=S+10
D=S-20
--------------------------------
S+(S-20)+(S+10)=155
S+S-20+S+10=155
3S-10=155
3S=165
S=165/3=55
---------------------------------
If S=55,
K=55+10=65
D=55-20=35
---------------------------------
Therefore, Sarah had worked for 55 hours, Kate had worked for 65 hours and Dave had worked for 35 hours.
3554 by 10 = 355.4
4678 by 40 = 116.95
