Best ResponseYou've already chosen the best response.0You are ordering a meal and have $15 to spend. The restaurant charges 6% sales tax. You plan to leave a 15% tip. The equation c=x+0.06x+0.15x gives the total cost c of your meal, where x is the cost before tax and tip. What is the maximum amount you can spend before tax and tip? So, I'll be able to do the math, I'm just not a 100% sure of how to start.

Best ResponseYou've already chosen the best response.0It says in the problem that x is the cost before tax and tip, so the set c to 15 and solve for x.

Best ResponseYou've already chosen the best response.0I would add up all the xs. x + 0.06x + 0.15x = 1.21x so 15 = 1.21x

Best ResponseYou've already chosen the best response.0Actually, 12.39 because it should go to cents, and you're looking for the maximum so you shouldn't round up on the cent

Best ResponseYou've already chosen the best response.0You have $85 in your bank account. Each week you plan to deposit $8 from your allowance and $15 from your paycheck. The equation b=85+(15+8)w gives the amount b in your bank account after w weeks. How many weeks from now will you have $175 in your bank account? Again, I can do the math, I just need help getting started.

Best ResponseYou've already chosen the best response.0175 = 85 + (15 + 8)w If I were you, I would gather like terms. This is one way to do it: 175  85 = 23w 90 = 23w
