Question

Write the expression in simplest form

Answer 1

Answer: It cost $43.

Explanation:

Answer 2

Firstly, they pay $7 as an entrance fee.

Then, they bought 5 hot dogs for an unspecified amount, x. The amount of hot dogs times x would equal the total price of the hot dogs.

Same principle for the popcorn and pretzels.

The expression would be 7 + 5x + 4y + 2z.

Now that we know the prices, we can plug them into the expression.

7 + 5 (4) + 4 (3) 2 (2)

7 + 20 + 12 +4 = 43

43
