Answer:
2(4 w + 3) = 62
width =7 length = 21
Step-by-step explanation:
For the perimeter you need :
2 times the width and 2 times the length (length =3w)
so
2(w+1) + 2 (3w+2) =
2w+2 + 6w+4 =
8w +6
you can factor this by:
2(4w+3)
8w +6= 62
8W = 56
w= 7 l= 21
2(7+1) + 2 (21+2)
16 + 46 = 62

It cost Julie $2 for the materials to make a bracelet that she plans to sell. She sells each bracelet for $7. What is her percent increase in price (also known as percent mark up)?
Answer:
350% Increase
Step-by-step explanation:
If Julie creates a single bracelet for $2, then sells a single bracelet for $7, her profit increase would be 350%. Since $7 / $2 = 3.5, then 3.5 * 100 = 350%. Hope this helped!
