Considering the formula H=Mc+mB+G, where H is the total price of a purchase, m is the number of items purchased, C is the cost per item, B is the tax on each item, and G is the total delivery charge, Solve for m
It doesn't really matter what any of the numbers mean. Also I think both `M` ` ` and `m` should be lower case and having that in mind the formula becomes
Now you group everything with `m` like this
Put G on the left hand side.
Divide by C+B to get m.` `
Hence, the formula for `m` is `m=(H-G)/(C+B)`.
