Please, help me out!

Answer 1

1.P=5S + 10C
2.650$

Answer 2

I need an explanation :(

Answer 3

if each shirt help earn a profit of 5$ then 'S' no. of shirts would earn a profit of '5S' $..
similarly
if each cap help earn a profit of 10$ then 'C' no. of caps would earn a profit of '10C' $..
therefore total profit is = 5S + 10C

further substitute value of S & C in equation for ans to 2.
we get P =5*30 +10*50
p=650$
