Step-by-step explanation:

the budget is 2800.so 4 tickets would cost 1660.

motel would cost 155. per night so add 1660+155'=1815

so subtract 2800.-1815=985

Then divide 985/155=6.35

So they could stay 7 days because they already had one day, then they  had enough left for 6 days so 1+6=7

1/f = 2π√(L/g)
1/(2πf) = √(L/g) . . . . . divide by 2π
1/(2πf)^2 = L/g . . . . . .square both sides
g/(2πf)^2 = L . . . . . . .multiply by g

L = g/(4π^2f^2) . . . . . . . matches the 1st selection
