Answer:
x = 13 and y = 5
Step-by-step explanation:
x + y = 18
x - y = 8
<u>Step 1: Find y</u>
x = 18 - y
(18 - y) - y = 8
18 - y - y - 18 = 8 - 18
-2y / -2 = -10 / -2
<em>y = 5</em>
<em />
<u>Step 2: Plug into x + y = 18 to get x</u>
x + 5 - 5 = 18 - 5
<em>x = 13</em>
<em />
Answer: x = 13 and y = 5

Dave pays $15 and tax is $1.2 so dave spent a total of $16.20.
Mel pays $20 and tax is $1.6 so Mel spent a total of $21.60.
All you need to do is convert the percent to a decimal, so take 8 and divide by 100 and you get 0.08. then you need to multiply the cost by the tax so 15*0.08=1.2 then you just add tax to original amount 15+1.2=16.2
