Answer:
465a + 605w = $10050
465a + 586w = 9822
465a + 605w = 10050
-465a - 586w = -9822
19w = 228
w= $12 each for wine
465a + 605(12)= 10050
465a + 7260= 10050
465a = 2790
a =$6 each apple cider
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17
4.50 /2 = 2.25
11.25/5 = 2.25
22.50/10 = 2.25
