Let no. of shirts be x.
Chris -- 7x
Brian --- 5x

Answer:
Step-by-step explanation:
The binomials are multiplied in the usual way, using FOIL or the distributive property:
(5 -2i)(3 -4i) = 15 -20i -6i +8i²
Since i² = -1, this becomes ...
= 15 -20i -6i -8 = 7 -26i
divide 2.49 by 5
2.49/5 = 0.498 rounded to nearest hundredth is 0.50 per pound
