Answer:
Ticket Taker Tony collects more tickets per minute.
Explanation:
In order to find out which ticket taker collects more tickets per minute, you need to solve for how many tickets each Ticket Taker collects per minute to compare. Since 90:5 and 128:8 are different ratios, you need to find the unit rate, or how many tickets each collects per minute. To find unit rate, you divide the numerator by the denominator:
Ticket Taker Tony:
=
Ticket Taker Tina:
=
Every minute, Tony collects 18 tickets, while Tina only collects 16, so Ticket Taker Tony collects more.
