Answer: $1.50/cookie
Step-by-step explanation:
Cookies = x
Water = y
5x + y = $8.75
y = 1.25
Plug in y-value into equation:
5x +1.25 = 8.75
5x = 8.75 - 1.25
5x = 7.50
x = 7.50/5
x = $1.50 for 1 cookie.
Multpiply first equation by 3 and second by 5 to clear nasty faractions
-13x-6y=21
15x+2y=25
now see which ones we can clear
we can clear y
multiply second equation by 3 and add to the first equation
-13x-6y=21
<u>45x+6y=75 +</u>
32x+0y=96
32x=96
divide both sides by 32
x=3
sub back
15x+2y=25
15(3)+2y=25
45+2y=25
minus 45 from both sides
2y=-20
divide both sides by 2
y=-10
x=3
y=-10
(3,-10)
It might be 7ab
Hope this helps!
