I am a 3 digit number. I have the largest 1 digit number in the tens place , the number that has the same place value always in the ones place and 4 in the hundredth place. Who am I?

265.1

Step-by-step explanation:

So his pay is essentially gonna be:

200 + (8 x 0.1 x 42) + (15 x 0.15 x 14) = ?

The 200 is his base pay he gets

He gets 10% of each magazine sold which can be found by multiplying 8 by 0.1 and then multiplying that by how many he sold (42).

Same rule applies for the books.

200 + 33.6 + 31.5

233.6 + 31.5

265.1
