You cannot use baking powder as a substitute for baking soda.
Generally you use 1 to 2 teaspoons of baking powder to each cup of flour.
Yes, 4 teaspoons of baking powder is generally considered a lot for a cake. Most cake recipes typically call for about 1 to 2 teaspoons of baking powder per cup of flour. Using too much can result in a cake that rises excessively and then collapses, leading to an undesirable texture and taste.
There are two tablespoons in an ounce, and three teaspoons in a tablespoon, so six teaspoons in an ounce. $0.99 / 6 teaspoons = $0.165 per teaspoon So about $0.17.

One to one and a half teaspoons of baking powder and a pinc to one half teaspoon of salt to a cup (125 g) of flour.
First of all, you can not buy just 2 teaspoons of baking powder. You would need to buy a package.The price depends on where you buy the baking powder and on the size of package you purchase.In the US, one teaspoon equals about 1/6 of an ounce. Two teaspoons would be 1/3 of an ounce.Looking at various websites, the price of one ounce of baking powder costs between $0.30 and more than $1.00. Taking the $0.30 per ounce, two teaspoons would cost about $0.10. Taking $0.99 per ounce, two teaspoons would cost about $0.33.
For one cup of self-rising flour I use 1 cup all-purpose flour, and add: 1 1/4 teaspoons baking powder AND 1/8 teaspoons salt
About 1.5 teaspoons. If the recipe calls for self raising flour and you don't have any then add 1.5 teaspoons of baking powder and 0.5 teaspoons of salt.
I don't know how much volume 4 oz. will be, but most recipes use the ratio of 1 teaspoon of baking powder to 1 cup of flour. Weigh the flour, measure it and find the amount of baking powder that way.
around 3 teaspoons, but this will vary according to the recipe.
the purpose of baking powder in a cake is to make it rise and not make it flat and if you put too much of baking powder your cake might burst in the oven/microwave what ever you use
