I'll tell you the answer but should I graph it, solve for x, solve for y, or what should I solve for?
What are you trying to do like simplify or what i can possibly help if i know
Answer:
Tax = $12 Tip = $18 Total Cost = $130
Step-by-step explanation:
tax = tax percentage x amount
0.12 x 100 = 12
tip = tip percentage x amount
0.18 x 100 = 18
The Total Cost
total cost = cost + tax + tip
100 + 12 + 18
Add them up and it would be
$130
10 = 2y + 4
6 = 2y
y = 3
18 = 10 + 2x
8 = 2x
x = 4
