and it states that states sales tax rate is 4% and county sales tax rates is 2%

Answer 1

In the following program, the variables stand for:

ts- Total sales

ctax- County sales tax

stax- State sales tax

ttax- Total sales tax

#include<stdio.h>  
double ts,ctax,stax,ttax;

void inputtotalsales()
{
        printf("\nEnter total sales: ");
        scanf("%lf",&ts);
}
void calculatetaxes()
{
        ctax=0.02*ts;
        stax=0.04*ts;
}

void displaytaxes()
{
        printf("\nCounty Sales Tax: %.2lf",ctax);
        printf("\nState Sales Tax: %.2lf",stax);
        printf("\nTotal Sales Tax: %.2lf",ctax+stax);
}

int main()                                                                     
{   
   inputtotalsales();                                                                           
   calculatetaxes();
   displaytaxes();
    return(0);                                 
}
