In a camping trip of 14 days:

Shirts needed = 14, Pair of jeans needed = 7

Step-by-step explanation:

Here, according to the question:

The pair of jeans required for 4 days  = 2 pairs

So, the number of jeans required in 1 day  = 2/4 = 1/ 2 pairs

⇒The number of jeans required in 2 days  =  

or, The pair of jeans required in 2 days  = 1 pair  ..... (1)

Similarly, The pair of shirts  required for 4 days  = 4

So, the number of shirts required in 1 day  = 4/4 = 1

⇒The number of jeans required in 2 days  =   1 x 2 = 2 shirts ... (2)

Now, packing for 14 days = Packing for 3  x (4) days   +  2 days

So, total shirts required for 14 days  = 3 x (shirt required for 4 days) +  shirt required for 2 days

= 3 x (4) + 2  = 14 shirts

or, total shirts required for 14 days camping = 14

Also, total jeans required for 14 days  = 3 x (jeans required for 4 days) +  jeans required for 2 days

= 3 x (2) + 1 = 7 pairs

or, total pair of jeans required for 14 days camping = 7

Hence, in a camping trip of 14 days:

Shirts needed = 14, Pair of jeans needed = 7

is there any photos or whatever?

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
