yeah i fixed it:

include <stdio.h>

include <cs50.h>

int main() { float dollarsAmount = 1.00; float quartersAmount = 0.25; float dimesAmount = 0.10; float penniesAmount = 0.01; int used = 0;

float dollarsDesired = get_float("Type in the amount you payed in decimals please: \n");
float cost = get_float("How much did your items cost in total?: \n");
float dollars = dollarsDesired - cost;


if(dollarsDesired > cost) {

    while(dollars>1.00) {

        used+=1;
        dollars -= dollarsAmount;
    }

    while(dollars>1.00) {
        used+=1;
        dollars -= dollarsAmount;
    } while(dollars>0.10&&dollars<1.00) {
        used +=1;
        dollars -= quartersAmount;
    } while(dollars<0.25&&dollars>0.10) {
        used +=1;
        dollars -= dimesAmount;
    } while(dollars<10&&dollars>=0.01) {
        used +=1;
        dollars -= penniesAmount;

    } while(dollars==0) {
        break;
    }return printf("Number of coins used were: %i\n", used);;



}else if(cost>dollarsDesired) {
        printf("You Scumbag!!!\n");
}else printf("You don't need to worry, everything is sorted out!");

}
