Question

At the movies, the cost of popcorn and the cost of

soda can be represented by the expressions shown
below. In terms of x, how could the price of one order
of popcorn and two sodas be expressed in simplest
form?

Popcorn: 3x + 5
Soda: 2x
A: 5x + 5
B: 10x
C: 7x + 5
D: 12x

Answer 1

The answer is option C: 7x + 5.

To find the cost of one order of popcorn and two sodas, we need to substitute the given expressions into the following formula:

Cost of one order of popcorn and two sodas = Cost of popcorn + Cost of two sodas

So, we have:

Cost of popcorn = 3x + 5

Cost of two sodas = 2x + 2x = 4x

Substituting these expressions into the formula, we get:

Cost of one order of popcorn and two sodas = (3x + 5) + 4x

Simplifying this expression, we get:

Cost of one order of popcorn and two sodas = 7x + 5

Therefore, the answer is option C: 7x + 5.
