An equation that expresses a relationship between two or more variables, such as Upper H equals nine tenths left parenthesis 220 minus a right parenthesis , is called Formula.

A formula is an equation that expresses a relationship between two or more variables.

The process of finding formulas to describe real-world phenomena is called mathematical modeling.

Such equations, together with the meaning assigned to the variables, are called mathematical models.

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
