되게 단순한 문제인데 묘하게 헷갈리네ㅎㅎ

#include <iostream>
#include <algorithm>
#include <vector>

using namespace std;

int main() {
	freopen("in1.txt", "rt", stdin);
	long long n;
	cin >> n;
	long long ans = 0;
	vector<long long> v;
	long long x;
	for (long long i = 0; i < n; i++) {
		cin >> x;
		v.push_back(x);
	}
	long long b, c;
	cin >> b >> c;
	for (long long i = 0; i < n; i++) {
		v[i] = v[i] - b;
		ans++;
		if (v[i] > 0) {
			if (v[i] % c == 0) ans += (v[i] / c);
			else ans += v[i] / c + 1;
		}


	}
	cout << ans << '\n';
	return 0;
}
