Php.22.50 for the first 10 grams or less, plus Php.5.75 for each additional gram beyond ten, plus a tax of 3%.
.......................... IN C++ BaSIC ......................................

what will be the formula code?
what will be i use?

help me...................

Well, the description gave you a lot of information so I would break down the problem like this:

1) calculate the cost (derived formula from description)
2) create UI to gather variables to calculate cost
3) create function to calculate cost using formula from 1 and variables from 2
4) display cost

So, from the description below, do you know how to create a formula to calculate the cost? How would you do this by hand if someone asked you (say in a Math class) for a general formula to calculate this?

Assume that the cost for sending a letter from the Philippines to New York is
Php.22.50 for the first 10 grams or less, plus Php.5.75 for each additional gram beyond ten, plus a tax of 3%.
