Step-by-step explanation:
Other solution
38.2 X 0.8 = 30.56 (20% off)
30.56 X 0.9 = 27.504 (Another 10% off)
Volume is given by:
V=(base area)×(height)
base area=bh
where:
b=base=8.5 cm
h=height= 4 cm
thus
base area=8.5×4=34 cm²
Thus the volume will be:
V=34×14
V=476 cm³
The club needs to make and sell 29 t-shirts in order to profit at least 150.
<em><u>Explanation</u></em>
Suppose , the number of t-shirts the club needs to make and sell is 
Selling price of each t-shirt is 15, so the total selling price of
t-shirts 
It costs 20 plus 9 per t-shirt to make the t-shirts. So, the total making cost of
t-shirts 
Now for getting profit at least 150 , the equation will be.....

It means the value of x should be at least 28.333...
<em>As here x is the number of t-shirts and it can't be in decimal , so </em><em>the minimum value of x will be 29.</em>
