Question

After the code that follows is executed, what is the value of discountAmount?

var discountAmount;
var orderTotal = 200;
if (orderTotal > 200) {
discountAmount = orderTotal * .3;
} else if (orderTotal > 100) {
discountAmount = orderTotal * .2;
} else {
discountAmount = orderTotal * .1;
}

Answer 1

An integer variable is defined and assigned an initial value of
`200`.

There is an if-else block in the next part of the code. In the first part, a condition is defined in case the value of the defined variable is greater than
`200`. But since the value of our variable is
`200`, we will proceed to the next block.

Since the value of our variable is greater than
`100`, we will follow the commands in the second block.

The expression
`.2` means multiplying the current number by
`0.2`.

Therefore, we will multiply
`200` by
`0.2`.

• The program output will be therefore as
  `40`.
