Question

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. (answers) ( 9,1.5, x, 1.5x)

Cost of lunch



Number of ride tickets



Total cost of ride tickets

Answer 1

The cost of lunch would be represented by 9 because there is only one lunch that was bought. 1.5 represented the price of each amusement ride. We know there are multiple rides because we must multiply it by the variable x, which represents the unknown quantity of tickets bought. 1.5x would thus give the total price paid for the tickets.
