Rico and halima are shopping for craft sticks, glue, and electrical tape for a science project. Together, they have $30 to spend on supplies. How should they spend their $30 if they need at least 1000 craft sticks?

Total Cost  :   y = 2.75 +  m (1) , where m = cost of each item

Step-by-step explanation:

The cost of admission and 3 samples = $5.75

The cost of  admission and 6 samples  = $8.75.

Cost is represented by y ,

The number of Samples = x

Let the admission charge is each case = $ a.

⇒ Total Cost  y = a + (Number of items tasted x Cost of each item)

So, according to the question:

First Case:

a +  3x =  $ 5.75

Second  Case:

a +  6x =  $ 8.75

Solving the above system of equations, we get a = $ 2.75

And , if a = $2.75  then    x = 1

Hence, the Total Cost y = 2.75 +  m (1) , here m = cost of each item
