Solve the Problem $\mathrm{t}$ -Shirts Sold as a Function of the Album Sales and Thousands)

Solve the problem.
-The following table shows the number (in thousands) of albums and t-shirts sold for three different months in the same year.

Model the number of $\mathrm{t}$ -shirts sold as a function of the album sales and time using a linear function of the form $s(a, t) =p a+q t+r(p, q, r$ constants) where $s$ represents thousands of $t$ -shirts sold to date, a represents thousands of albums sold to date, and $t$ represents time in months since April of that year.

A) $p=0.02, q=10, r=40$
B) $p=10, q=0.02, r=-40$
C) $p=0.02, q=10, r=-40$
D) $p=0.2, q=-10, r=-40$
