    You 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.

    You just have to find x.

    It says in the problem that x is the cost before tax and tip, so the set c to 15 and solve for x.

    Well I understand that, and I understand how to find it, but I'm just slightly confused by my first step. it'll be clear once I understand it. Mind explaining and getting me on the right track?

    I would add up all the xs. x + 0.06x + 0.15x = 1.21x so 15 = 1.21x

    Actually, 12.39 because it should go to cents, and you're looking for the maximum so you shouldn't round up on the cent

    You 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.

    175 = 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

    yes. I got that too :) If you don't know how to start, you should add the xs together and the numbers together.

    One more? This one is different. It's fractions, and I always get myself mixed up with those.

    Haha they are quite a pain. 2/3(c-18)=7 (the 2 is over the 3, the parentheses are next to that)

    \(\Large \frac{2}{3} (c-18) =7 \) \(\Large \frac{2}{3}c - \frac{2}{3}(18) =7 \) \(\Large \frac{2}{3}c - \frac{2}{1}(6) =7 \) \(\Large \frac{2}{3}c - (12) =7 \) \(\Large \frac{2}{3}c =19 \) \(\Large c= 19* \frac{3}{2} \)
