//I'll let x = $5, y = $10
x + y = 13
5x + 10y = 90
So, y = 13 - x
5x + 10(13 - x) = 90
5x + 130 - 10x = 90
-5x = -40
x = 8
Answer:
It $29.75
Step-by-step explanation:
From the second equation ,we can know that y=3.25x+0.75
plug it into the first equation
-4.5x-2(3.25x+0.75)=-12.5
-4.5x-6.5x-1.5=-12.5
-11x=-11
x=1
plug it back into the second equation, y=3.25x+0.75=4
the answer would be (1,4)
I think 32! If it’s wrong I’m sorry lols
