I take it that only 7 stamps are misplaced and that we are asked for the total value of the stamps including those which have been misplaced.
If each is worth $0.15 then, the total worth of 7 stamps is $1.05. Then, we add this value to the value of his remaining stamps, $5.55, the answer would be $6.60.

Well, first you would estimate all the terms: 10.2 to 10, 2 to 2(keep the same), 3.7 to 4, and eight to eight.
So you have 10 x [(2 x 4) + 8]
then you would evaluate this expression using order of operations
10 x [(2 x 4) + 8]
10 x [8 + 8]
10 x 16
160
