#define tax_rate 12.50
#define americano_rate 3500
#define caffe_l_rate 4000

int americano, caffe_l, espresso, vanilla_l = 0;
float subtotal;
float taxam;
float total;

printf(how many americanos were sold? );
scanf(%d, &americano);
printf(how many caffe lattes were sold? );
scanf(%d, &caffe_l);
printf(how many espressos were sold? );
scanf(%d, &espresso);
printf(how many vanilla lattes were sold? );
scanf(%d, &vanilla_l);
subtotal = (float)americano*americano_rate + caffe_l*caffe_l_rate + espresso*espresso_rate + vanilla_l*vanilla_l_rate;
taxam = (float)subtotal * tax_rate / 100.00f;
total = subtotal + taxam;float로 type conversion 했는데도 에러뜨는데 어떻게 하면 에러를 없앨 수 있을까요?

에러난 이유와 조언좀 부탁드립니다.
