JavaScript Loop

Question

Hello, I am working on a program and I am almost done, the problem I am encountering is that I cannot come to a way that from every 3 sandwiches the first two cost 3.50$ and the third 2$. How can I make a loop to do this. if I want to see the total cost of 10 sandwiches.

Answer 1

I'm not sure if I fully understood your question, but maybe this can give you an idea:

var totalCost = 0;
for(var sandwich = 1; sandwich <= 10; sandwich++)
{
if(sandwich % 3 == 0)
{
console.log("$2 -> sandwich " + sandwich);
totalCost += 2;
}
else
{
console.log("$3.50 -> sandwich " + sandwich);
totalCost += 3.50;
}
}
console.log("Total cost: " + totalCost);

Answer 2

for(var i = 0; i<= 10; i++){

if(i%3!=0){
console.log(i+"this first and second one cost 3.50quot;);
}

if(i%3==0){
console.log(i+"this third one cost 2quot;);
}
}
