Question

Write an equation for Income, I, for selling n t-shirts.

A) I = 150 + 12n

B) I = 150n

C) I = 162n

D) I = 12n - 250

Answer 1

The equation for Income, I, for selling n t-shirts is I = 150 + 12n.

Step-by-step explanation:

The equation for Income, I, for selling n t-shirts is I = 150 + 12n.

This equation represents a linear relationship between the number of t-shirts sold (n) and the income earned (I). The constant term 150 represents the fixed income that does not depend on the number of t-shirts sold. The coefficient of n, which is 12, represents the income generated from each t-shirt sold.

For example, if you sell 10 t-shirts, the income would be I = 150 + 12(10) = 150 + 120 = 270.
