Answer:
~ 15 %
Step-by-step explanation:
116.4 - 98.3 = 18.1
18.1 / 17.5 = 1.034 SD ABOVE the mean

Answer: the costs would be the same when 12 shirts are ordered.
Step-by-step explanation:
Let x represent the number of shirts for which both costs would be the same.
One company charges $9.65 per shirt plus a set up fee of $43 dollars. This means that the total cost of ordering x shirts from the first company is
9.65x + 43
Another company charges $8.40 plus a 58 dollar fee. This means that the total cost of ordering x shirts from the second company is
8.4x + 58
Therefore, for the costs to be the same,
9.65x + 43 = 8.4x + 58
9.65x - 8.4x = 58 - 43
1.25x = 15
x = 15/1.25
x = 12
3.421 x 7= 23.947
