Monica went to the fair and paid for her lunch as well as tickets to ride several rides. The expression 1.5x + 9 represents her total costs.

What do the different parts of the expression model?



Drag the parts of the expression into the boxes to match each description.


Cost of lunch Number of ride tickets Total cost of ride tickets

Answer choices: 9, 1.5, x, 1.5x

Respuesta :

She ate only one lunch, so the cost of the lunch is a constant - it is the 9

9 - cost of lunch

Now, we don't know how many rides she took- it will be represented by a variable, x, 

x-number of rides

and each ride must have cost 1.5

1.5- cost of each ticket

so 1.5x was the total cost of the ride tickets

and 1.5x+9 is the total cost!
