Answer:
c) $8.40
Step-by-step explanation:
To do this you would start by multiplying $8 and 5% to find the additional cost. To multiply a percentage you turn it into a decimal so it would look like this: [tex]8*.05[/tex] which equals [tex].40[/tex]
Then, you're going to take this number and add it to the original cost of the garment to get your budget ([tex]B[/tex]). So you would have [tex]8+.40[/tex] to get a total budget of $8.40 per garment.
Looking at your options I can see that there's most likely a typo, and we can assume that option c) is meant to be $8.40, so I would recommend choosing that one and then telling your teacher that there's a potential typo :)
