During a fundraiser, students in Math Club make a $0,50 profit for every candy bar they sell
Let n represent the number of candy bars the club sells.
Lett represent the total profit earned, in dollars.
What is the total profit earned for selling 10 candy bars?

I got two answer when I solved it but I’m not sure which one is correct

Here what I got

For the first time I tried it
0.50x10=5
Or
0.50+0.50 +0.50 +0.50 0.50 +0.50+0.50+0.50+0.50= 4.5

I’m not sure if I’m correct or which is the right answer can someone expían ?
