I need help its only 2 questions so plz answer respectfuly and correctly. And plz explain ur answer.

1) To find out the markup, you have to do 1300 (Lucas Paid) and the profit (.20) which is $260. So to find the original price, you subtract 260 from what Lucas paid, which when you do the math, is $1040, so the original price is $1040

2) The Unit Rate is 5

I hope this helps, and have a great rest of your day. :)
