The cost per friend is $6.84.
<h3>What is the cost per friend?</h3>
The first step is to determine the total cost of the vegetables the two friends bought.
Total cost of the vegetables = ( 1 x $2.82) + 4.19 X 2 + (1.24 x 2) = $13.60
In order to determine the cost per friend, divide the total cost of the vegetables by the number of friends that purchased the items.
$13.6 / 2 = $6.84

For ease of solving, let's first find the rate of Mia and Luke per minute. Since Mia can do 4 pieces every 3 minutes, then she can do

of a piece per minute. Luke on the other hand can do

of a piece per minute.
To find how many pieces they made, we first need to find the time it took for them to make the pieces. We assign

as the time Mia spent making origami. Since Luke spent 5 more minutes, we can denote his time as

.
Putting this into an equation we'll get:




Therefore, Mia made pieces of origami for 39 minutes. Knowing this, we can find out the number of pieces of origami she made:
ANSWER: Mia made 52 pieces of origami.
The first one is 18.5. That was a result of dividing decimals.
Second one is $4.82 because you are trying to find the unit rate.
Third is 2608.75 dollars earned. You multiply the number of memberships with cost, 152. Now you add that with the monthly earnings, resulting in that answer.
