Answer 1

There are only 4 items not 5
No need to get percentage just increase prices
No need to print value one by one just print prices
for(let i=0;i<4;++i){
prices[i] += increase;
}
console.log(prices)

Answer 2

for(let i=0;i<4;++i){ // array has only 4 elements, so only loop 4 times..
prices[i] += prices[i]*(increase/100);
}// use prices[i] , not prices here.

No need of another variable, you can use the same.
Also just print prices
console.log(prices); //this is enough

Answer 4

Create a new variable that prompt use for input, then add to each of the given array.
Something like this
function main() {
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
let increase = +prompt ("enter a no");
let newPrices = prices.map((value) => value + increase)
console.log(newPrices )
}
main()

Answer 5

Your new array has 5 elements. But original has only 4 elements. No need new array.
And to display just use
console.log( newprices ) ; // how you want to display?
edit:
d shaw
console.log(...newprice); // space separated
console.log("[",newprice,"]");

Answer 6

What is your difficulty there..?
Just add input value to each array element and display array..

Answer 7
