Eleven years old is Sam. Sam is half as old as Ross. How old will Sam be when Ross turns 50?

Answer: 39

If Ross is currently twice as old as Sam and Sam is 11 years old, then Ross is currently 2×11=22 years old. If Ross is 50 years old, then the age gap between Ross and Sam is 50−22=28 years. In the future, Sam will continue to age, so to find out how old Sam will be when Ross is 50, you add the age gap to Sam's current age: 11+28=39 Therefore, when Ross is 50 years old, Sam will be 39 years old.

During the week, Kim leases an electric scooter to run errands. Her total scooter bill for Monday and Tuesday was $4.25. Her expenses for Wednesday and Thursday were $6.50 per day. She just spent $7.00 on Friday. What is the daily average cost?

Answer: $4.85

To find the average daily cost, you need to add up the total costs for the week and then divide by the number of days. Monday + Tuesday: $4.25 Wednesday + Thursday: $6.50 + $6.50 = $13.00 Friday: $7.00 Now, add these daily costs: $4.25 + $13.00 + $7.00 = $24.25 There are 5 days in the week (Monday through Friday). Average daily cost = Total cost / Number of days Average daily cost = 24.25/5 Average daily cost = 4.85 So, the average daily cost for Kim's electric scooter is $4.85.
