Ms. Sue,
You need to add all four numbers first. Then divide the sum by 4 to find the mean.

the median is 105 and 107
and i don't about mode 
4th grade 
Ms. Sue,
The median is half way between 105 and 107  so the median is 106.
This set of numbers doesn't have a mode. All of the numbers are different.
How do you think you can solve the last problem?

10.001.50=$8.50 he receive back
and my son did 2:50+1:50=4:00 then he subtract 10:004:00 =$6:00 he receive back 
4th grade 
Ms. Sue,
He played 4 games. So we multiply 1.50 times 4 = $6.00.
He paid $2.50 to rent shoes.
$2.50 + $6.00 = $8.50
$10.00  8.50 = ? change
