Answer:
150 shirts and 75 jeans
Step-by-step explanation:
s = shirts
j = jeans
12s+28j = 3900
The profit on the shirts is 70 percent so we multiply 12 by .7
12*.7 = 8.4
The profit on the jeans is 125 percent so we multiply 28 by 1.25
The profit was 3885
28*1.25 = 35
8.4s+ 35j=3885
We now have 2 equations and 2 unknowns
12s+28j = 3900
8.4*s+ 35j=3885
I am going to solve by elimination
Multiply the first equation by -.7
-.7 (12s+28j )= -.7*3900
-8.4s -19.6j=-2730
Add this to the second equation
-8.4s -19.6=-2730
8.4s+ 35j=3885
------------------------
15.4j = 1155
Divide each side by 15.4
15.4j/15.4= 1155/15.4
j = 75
Now we need to find the shirts.
We will substitute j=75
12s+28(75) = 3900
12s +2100 = 3900
Subtract 2100 from each side
12s = 3900-2100
12s = 1800
Divide by 12
12s/12 = 1800/12
s =150
