#3. Hour ≤ 35 (If hours are less than or equal to 35), then she makes $14.50 per hour.  
Hour > 35 (If hours are greater than 35), then she makes $14.50*1.5 per hour.

48h - 35h  = #Hours more than 35
48h - 35h = 13

35h*$14.50/h + 13h*($14.50/h*1.5) = $790.25

#4.
Round trip = $398.60
Hotel = $115.70*n (n in this case, is the # of nights)
Cab = $40.00

$398.60 + $115.70*2 + $40.00 = $670.00
