Question

Five friends bought admission tickets the museum and a box lunch.the cost of each admission ticket was $11.75.each box lunch cost $5.write two equivalent expressions and then find the total cost.

Answer 1

Cost of the admission tickets: 11.75x

Cost of the box lunch: 5x

Expressions to find the total cost = (1) ....... 11.75x + 5x

That is equivalent to: (2) .......... (11.75 + 5)x = 16.75x.

Now calculate the cost for x = 5 using both expressions:

1) 11.75(5) + 5(5) = 58.75 + 25 = 83.75

2) 16.75(5) = 83.75

Of course you got the same result with both expressions.

Answer 2

Answer:

$83.75

Step-by-step explanation:

5(11.75 + 5) 5(11.75) + 5(5)
