I have this function:

```  getApplyAll (arr ){
return   100 * arr.reduce((sum, n) => sum + +n.apply, 0) / arr.reduce((sum, n) => sum + +n.count, 0);
};
```

The function itself works correctly. The problem is that it displays the result in this form: `35.294117647058826`. How can reduce the result to such a `35.29`

use `toFixed(2)` function.

```getApplyAll (arr ){
let result = 100 * arr.reduce((sum, n) => sum + +n.apply, 0) / arr.reduce((sum, n) => sum + +n.count, 0);
return result.toFixed(2)
};
```

Rewriting Equations & Formulas (Learn Algebra 2), Sounds nice but what is a formula? Formulas are mathematical equations that are used to solve for something like area. Formulas show how variables, which are  Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

```getApplyAll (arr ){
let result = 100 * arr.reduce((sum, n) => sum + +n.apply, 0) /
arr.reduce((sum, n) => sum + +n.count, 0);
return Math.round(100 * result)/100
```

};

If you are using `toFixed` don't forget that the result will be a string (not a number) so you may have to convert

```result = parseInt(result)
```

Algebra Examples | Functions, Rewrite formulas and equations. 1. Solve for t in the equation -9 = t + 4s. 2. Solve for A: B = 5/7  Let's look at the equation for the surface area of a right pyramid. The formula is surface area is equal to the area of the base plus 1/2 times the perimeter of the base times the slant height. This time, we will isolate the perimeter (P). To start, we will subtract the B from both sides as seen in blue.
