Answer :

1)

The information tells us the total cost of purchasing poster board and stick for 'x' number of students.

2)

With three(3) extra boards and five(5) extra stick-on letters, the expression to represent the cost of buying supplies for 'x' number of students is:

3x + 4x + (3 x 3x) + (4 x 5x)= 3x+4x+9x+20x= 36x
