A club decides to sell t-shirts for 15 as a fundraiser. It costs 20 plus 9 per t-shirt to make the t-shirts. Write and solve an

zepelin [54]

The club needs to make and sell 29 t-shirts in order to profit at least 150.

Explanation

Suppose , the number of t-shirts the club needs to make and sell is $x$

Selling price of each t-shirt is 15, so the total selling price of $x$ t-shirts $= 15x$

It costs 20 plus 9 per t-shirt to make the t-shirts. So, the total making cost of $x$ t-shirts $= 20+9x$

Now for getting profit at least 150 , the equation will be.....

$15x-(20+9x)= 150\\ \\ 15x-20-9x=150\\ \\ 6x-20=150\\ \\ 6x=150+20=170\\ \\ x= \frac{170}{6}=28.333....$

It means the value of x should be at least 28.333...

As here x is the number of t-shirts and it can't be in decimal , so the minimum value of x will be 29.
