Full solution

Q. Heather is a cashier. She can ring up 1212 customers in 99 minutes.\newlineAt this rate, how many minutes does it take her to ring up 44 customers?\newline\square minutes
  1. Calculate time per customer: Heather rings up 1212 customers in 99 minutes, so to find out how long it takes her to ring up 11 customer, we divide the minutes by the number of customers.\newline99 minutes ÷\div 1212 customers = 0.750.75 minutes per customer.
  2. Determine time for 44 customers: Now, we need to find out how long it takes to ring up 44 customers. We multiply the time it takes to ring up 11 customer by 44.\newline0.750.75 minutes/customer ×\times 44 customers = 33 minutes.
