Question

This is what i have so far, but i need help trying to fix the tax so that it can work correctly can someone help me

#include <stdio.h>
int main()
{
  float cost,labourCost,discountcost,Tax; /*I declared variables in float to
reduce loss of precision*/
  int discount,length,width,area; /*Here i declared usable integer varibles*/
  printf("Enter length in feet (integer):");
  scanf("%d",&length); /*Reading length from user */
  printf(" Enter width in feet (integer): ");
  scanf("%d",&width);/*Reading width from user */
  printf(" Enter Discount rate: ");
  scanf("%d",&discount);/*Reading discount from user */
  printf(" Enter Cost per square ft. (float): ");
  scanf("%f",&cost);/*Reading cost per square feet from user */
  printf(" Length: %d ",length); /*Printing length */
  printf(" Width: %d",width);/*Printing the width */
  area=length*width;/*calculating the area */
  labourCost=0.35*area;/*calculating labour cost which is used at printing output */
  discountcost=(area*cost*discount*0.01);/*calculating the discount cost */
  Tax=(.07*Sub total);
printf(" Area is: %d",length*width);/*This is where I print the program */
/*------------------------Calculatoins Here-------------------------- */
        printf("             Charges");
  printf(" Description Cost Per Sq. Ft Charges");
  printf(" ----------- --------------- ----------");
  printf(" carpet %f %f",cost,            (area*cost));
  printf(" Labour 0.35 %f",                labourCost);
  printf(" Installed Price %f",           ((area*cost)+labourCost));
  printf(" Discount %d %f",discount,      discountcost);
  printf(" Sub total %f",    ((area*cost)+labourCost)-discountcost);
  printf(" Tax %d %f, (.07*Sub Total)");
  printf(" Total %f",   ((area*cost)+labourCost)-discountcost+Tax);
  return 0;
}
This is C programming

Explanation / Answer

MADE THE CHANGES IN BOLD

===============================================

#include <stdio.h>
int main()
{
  float cost,labourCost,discountcost,Tax, sub_total; /*I declared variables in float to reduce loss of precision*/
  int discount,length,width,area; /*Here i declared usable integer varibles*/
  printf("Enter length in feet (integer):");
  scanf("%d",&length); /*Reading length from user */
  printf(" Enter width in feet (integer): ");
  scanf("%d",&width);/*Reading width from user */
  printf(" Enter Discount rate: ");
  scanf("%d",&discount);/*Reading discount from user */
  printf(" Enter Cost per square ft. (float): ");
  scanf("%f",&cost);/*Reading cost per square feet from user */
  printf(" Length: %d ",length); /*Printing length */
  printf(" Width: %d",width);/*Printing the width */
  area=length*width;/*calculating the area */
  labourCost=0.35*area;/*calculating labour cost which is used at printing output */
  discountcost=(area*cost*discount*0.01);/*calculating the discount cost */

sub_total=((area*cost)+labourCost)-discountcost;

  Tax=(.07*sub_total);
printf(" Area is: %d",length*width);/*This is where I print the program */
/*------------------------Calculatoins Here-------------------------- */
        printf("             Charges");
  printf(" Description Cost Per Sq. Ft Charges");
  printf(" ----------- --------------- ----------");
  printf(" carpet %f %f",cost,            (area*cost));
  printf(" Labour 0.35 %f",                labourCost);
  printf(" Installed Price %f",           ((area*cost)+labourCost));
  printf(" Discount %d %f",discount,      discountcost);
  printf(" Sub total %f",   sub_total);
  printf(" Tax %d %f", Tax);
  printf(" Total %f",   sub_total+Tax);
  return 0;
}
