return cost;
}
public static void main(string args) {
int costreturned = calculatecost(19, 5);
system.out.println(costreturned);
}
}

Explanation:

Step1: Analyze the age condition

The age is 19, which satisfies \(18\leq age < 28\).

Step2: Analyze the units condition

The units is 5, which satisfies \(units>1\).

Step3: Calculate the cost

According to the formula \(cost=(units - 1)\times400\), substitute \(units = 5\) into it: \(cost=(5 - 1)\times400=4\times400 = 1600\).

Answer:

1600
