The Honor Society decided to have t-shirts made for each member. There is a screen printing fee of $15 and each t-shirt costs $4.75. The total bill for having the t-shirts made was $143.25.
To find the answer, here's the equation: 143.25/15+4.75 = 143.25 / 19.75 which is about 7.25. We can assume that about 8 people are in the honor society. I might be wrong, though...
