Lesson 6: Two-step equation word problems

Using information from the Super Yoga word problem, explore all the possible combinations and create equations which express the possibilities. Let's figure out which plan is best! Created by Sal Khan.

• How would you account for when you hit the second month and an additional \$20 is spent?
• I guess you could modify your equation to include a second variable (let's make it 'M') that represents the number of months, thus:

C = 20*M + 8*S

This means that you also have to include another column to the table, 'M', which tells you in which month you currently are.
• How many Sessions are per month though? If there is 1 each week he would only have to pay \$20 plus the \$8 for the sessions.
• I guess you just have to assume that a session is there whenever you want it.
• on every math test, I always be like aww man I wish I was Khan who else?
• Just like me, he has years of experience on you, so if you enjoy math and look back 10 years from now, you will say how easy this was looking back, but new things always take time to learn. I am proof that you can still teach old dogs new tricks.
• Why would you have to pay an addition of \$8 if you already have the monthly plan of \$20
• The monthly plan simply gives you a \$4 discount per session(when compared to the trial plan).

• This is how I do this in my head: I need to make up the \$20 extra for the monthly plan in savings to make it worth it. The savings is made through the difference in per-sessions cost, which is \$4 (\$12 - \$8). So how many sessions does it take until I've absorbed the \$20 fee (how many times does 4 go into 20)? 5. So I know that the cost equals out at 5 sessions, and beyond that, monthly plan is better. Thoughts? Maybe I'm missing the point?
• That's right, actually. At 5 sessions in a month, both the Trial Plan and the Basic Plan cost \$60. However, if you attend 6 sessions in a month, the Trial Plan will cost \$72 and the Basic Plan will cost only \$68.
• Bruh I would just take the trial plan. You only pay 12 bucks. Why even get a membership it's not even anything extra.
