# 30 Days of Code - Day 2: Operators

# Objective

In this challenge, you’ll work with arithmetic operators. Check out the Tutorial tab for learning materials and an instructional video!

# Task

Given the *meal price* (base cost of a meal), *tip percent* (the percentage of
the *meal price* being added as tip), and *tax percent* (the percentage of the
*meal price* being added as tax) for a meal, find and print the meal’s *total
cost*.

**Note:** Be sure to use precise values for your calculations, or you may end
up with an incorrectly rounded result!

# Input Format

There are 3 lines of numeric input:

The first line has a double, `mealCost`

(the cost of the meal before tax and
tip).

The second line has an integer, `tipPercent`

(the percentage of `mealCost`

being added as tip).

The third line has an integer, `taxPercent`

(the percentage of `mealCost`

being
added as tax).

# Output Format

Print `The total meal cost is totalCost dollars.`

, where `totalCost`

is the
rounded integer result of the entire bill (`mealCost`

with added tax and tip).

# Sample 00

12.00
20
8
```

output00.txt
`15`

## Explanation

Given:

`mealCost = 12`

, `tipPercent = 20`

, `taxPercent = 8`

Calculations:

`tip = 12 * (20 / 100) = 2.4`

`tax = 12 * (8 / 100) = 0.96`

`totalCost = mealCost + tip + tax = 12 + 2.4 + 0.96 = 15.36`

`roud(totalCost) = 15`

We round `totalCost`

to the nearest dollar (integer) and then print our result:

```
The total meal cost is 15 dollars.
```

# Sample 01

input01.txt```
15.50
15
10
```

output01.txt
`19`

# Solution

`main.go`

```
package main
import (
"fmt"
)
func main() {
var (
mealCost float64
tipPercent, taxPercent int
total float64
)
fmt.Scan(&mealCost)
total += mealCost
fmt.Scan(&tipPercent)
total += float64(tipPercent) / 100 * mealCost
fmt.Scan(&taxPercent)
total += float64(taxPercent) / 100 * mealCost
fmt.Println(int64(total + 0.5))
}
```
