First, you have to add up the cost of each meal and drink:
12.50 + 12.50 + 1.50 + 1.50 = 28
$28 is the cost before the tip. Now multiple 28 by .18 to find the tip:
28 x .18 = 5.04
The tip was $5.04. Add the 28 and the 5.04 to get the total cost:
28 + 5.04 = 33.04
ANSWER:
The total cost was $33.04
Answer:
x=10, y=5
Step-by-step explanation:
For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.
x-2y=0
x=2y
You can substitute 2y as x on the first equation (x+4y=30).
2y+4y=30
6y=30
y=5
Plug y=5 into any equation.
x+4(5)=30
x+20=30
x=10
