Answer:
$ 12.6 / h
Step-by-step explanation:
5% of 12 = 0.05 * 12 = 0.6
Now adding it to the amount he makes, since it is a raise:
0.6 + 12 = 12.6 $ / h
Another (and faster) way to calculate it:
1.05 * 12 = 12.6
12.56 = 2(3.14) square root (L/32)
12.56 = 6.28 square root (L/32)
square root (L/32) = 2
L/ 32 = 2^2
L/ 32 = 4
L = 4 (32)
L = 128
The percent markup is 11.11 %
<em><u>Solution:</u></em>
Given that, the store buys 100 shirts at a cost of $ 2700
Let us find the cost of 1 shirt

The store sells them at $ 30 each
Therefore,
Cost price of 1 shirt = $ 27
Selling price of 1 shirt = $ 30
Markup price = Selling price - Cost price
Markup price = 30 - 27
Markup price = 3
Thus markup price is $ 3
<em><u>The percent markup is given as:</u></em>

Thus the percent markup is 11.11 %
