25/4 = 6.25 per t-shirt <== unit price
the error that was made is the student put the number of t-shirts over the price, instead of the price over the number of t-shirts.
4/25 = 0.16
I do not have the answer but can I have BRAINLIEST
Firstly arrange the data pont from smaller to larger:
22------27--------46--------57------------73------------78---------------90
1st Q Median 3rd Q
Total Range : 90-22 = 68
Interquartile range: Q₃ - Q₁ = I = 78 -27 = 51
I hope the above is self explanatory
0.89 Would Be 89% and 1/2 Would Be 50%
The answer is 3.083333333333333....
