MArishka [77]

Answer:

Step-by-step explanation:

Using the rule of logarithms

log x^{n} ⇔ nlogx

Given

190 = 200^{b} ( take the natural log ln of both sides )

ln190 = ln200^{b} = bln200 ( divide both sides by ln200 )

\frac{ln190}{ln200} = b

The tour costs £359 per person. You have to pay a deposit of £78 in advance. How much more do you need to pay
dimaraw [331]
The cost of the tour= £359.

The deposit is just an initial pay, which is a part payment of the total cost

If you pay a deposit of £78 out of £359, Then you need to subtract £78 from £359 to obtain,

359-78=281 pounds.

Therefore you need to pay £281 more.
