Answer:
200 x .39
Step-by-step explanation:
200 x .39= 78
Loss per week is -$3
Profit per can is $1.00 - $0.30 which is $0.70
Therefore then equation is
p = 0.7x - 3
Answer:
x=-12,y=3
Step-by-step explanation:
1/2x+6y=12
y=x+15
since y=x+15
substitute y in first equation, we have
1/2x+6(x+15)=12
open the bracket
1/2x+6x+90=12
1/2x+6x=12-90
x/2+6x= -78
13x/2=-78
13x=2×-78
x=-12
Now x=-12, put x=-12 in the second equation, we have
y=x+15
y=-12+15
y=3
hope it helps
