3. A local pizza restaurant has two options for birthday parties; the Premium Plan and the
Basic Plan.
• The Premium Plan charges $20 for a cake and $5 per child for pizza.
The Basic Plan charges $6 per child for pizza and the customer brings their own cake.
If x represents the number of children at the party, which equation represents the
situation when the cost of The Basic Plan will cost the same as The Premium Plan?
O
A. 20x + 5 = 6
O
O
O
B. 25x = 6
C. 20 + 5x = 6x
D. 25x = 6x

Most likely C .

Step-by-step explanation:

The premium plan charges 20 dollars per cake. (+ 20) and $5 per child (5x) for pizza.

The premium plan would represent:

The basic plan would charge $6  per child for pizza.

This would be:

In a equation when the cost of the premium plan is the same as the basic plan, would be the best for modeling.  

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
