Question

I need help with JavaScript.


The value of salesCost is 20. After the following code executes, what is the value of salesTotal?

if (salesCost <= 25)
salesTotal = salesCost * 1.5;
else
salesTotal = salesCost * 1.25;

Answer 1

do you understand how if/them/else works?

Answer 2

yea but with the math it makes it confusing

Answer 3

Okay great. So according to the value you have for salesCost, which condition is going to be executed?

Answer 4

sales total I think but yet not sure which number

Answer 5

Ok you have two conditions that will be executed.

salesTotal = salesCost * 1.5;
OR
salesTotal = salesCost * 1.25;

Now look at your conditional statement:

IF salesCost is less than or equal to 25 THEN salesTotal = salesCost * 1.5;

OTHERWISE (else) salesTotal = salesCost * 1.25;

Looking at it this way which calculation do you think will be performed?

Answer 6

the 1.5 one

Answer 7

Please forgive my delay. I'm helping you as I cook dinner. lol

You are correct. Since salesCost is 20 and 20 <25 then the first condition is going to execute.

In that condition we have another variable salesTotal. To this variable we are assigning the value of salesCost times 1.5

OR

salesTotal = 20*1.5

OR

salesTotal = 30

Does that make sense?

Answer 8

yes thank you for your help

Answer 9

You are very welcome.
