Let's say stress ball cost x and t shirt cost y
8x+5y=111.75
12x+4y=102.00→3x+y=25.5→y=25.5-3x
8x+5(25.5-3x)= 111.75
8x+127.5-15x=111.75
-7x=-15.75
x=2.25
12x+4y=102
12(2.25)+4y=102
27+4y=102
4y=75
y=18.75
d is the correct answer

population standard deviation 
Std error = 
Margin of error for 95%
= 
Since sample size is number of items it cannot be indecimal.
So we can round off to the next high integer on a safer side.
