Studdy Solution

STEP 1

Assumptions1. Rosa spent a total of $11.52. She bought8 candy necklaces for each of her two friends3. Each necklace was the same price

STEP 2

First, we need to find the total number of necklaces Rosa bought. She bought8 necklaces for each of her two friends, so we can find the total number of necklaces by multiplying the number of necklaces per friend by the number of friends.
Total necklaces=Necklaces per friendtimesNumber of friendsTotal\, necklaces = Necklaces\, per\, friend \\times Number\, of\, friends

STEP 3

Now, plug in the given values for the number of necklaces per friend and the number of friends to calculate the total number of necklaces.
Total necklaces=8times2Total\, necklaces =8 \\times2

STEP 4

Calculate the total number of necklaces.
Total necklaces=8times2=16Total\, necklaces =8 \\times2 =16

STEP 5

Now that we have the total number of necklaces, we can find the cost of each necklace by dividing the total cost by the total number of necklaces.
Cost per necklace=Total cost/Total necklacesCost\, per\, necklace = Total\, cost / Total\, necklaces

STEP 6

Plug in the values for the total cost and the total number of necklaces to calculate the cost per necklace.
Cost per necklace=$11.52/16Cost\, per\, necklace = \$11.52 /16

STEP 7

Calculate the cost per necklace.
Cost per necklace=$11.52/16=$0.72Cost\, per\, necklace = \$11.52 /16 = \$0.72Each necklace costs $0.72.
