This document contains formulas for calculating percentages, totals, and costs over time. It includes formulas to calculate 10%, 15%, and 20% of a value in cell C4 and subtract that from the total. It then sums these totals in cell E4, G4, and I4. Additional formulas multiply the final sum by 7 to calculate total weekly cost, add values to the weekly cost for bus or plane transportation costs, and display the results.

1. FORMULAS:
10%=C4*$D$3
TOTAL=C4-D4
15%=C4*$F$3
TOTAL=C4-F4
20%=C4*$H$3
TOTAL=C4-H4
SUMA FINAL=E4+G4+I4

2. FORMULAS:
COSTO TOTAL X SEMANA =SUMA(C29:I29)*7
COSTO TOTAL X BUS =(J29+$C$33)
COSTO TOTAL X AVION =(J29+$C$34)
