The relationship between the number of tickets purchased and the total price should be proportional. On the sign below, select the price that was marked incorrectly.

b. $3.50

Step-by-step explanation:

The computation of the price that market incorrectly is

As per the attached figure it is mentioned that

The price of one ticket is $0.75

Now for 5 tickets it would be

= $0.75 × 5

= $3.75

For 10 tickets, it would be

= $0.75 × 10

= $7.5

And for 20 tickets, it would be

= $0.75 × 20

= $15

Therefore the option B is incorrect as the answer that come would be $3.75 not $3.50
