Let x be amount of music lessons
Member = 100 + 20x
Non member = 30x
Must be same, so 100 + 20x = 30x
Solve for x:
Group like terms.
100 = 30x - 20x
100 = 10x
100/10 = x
x=10
10 music lessons for member and non member to have same costs of $300.
Im not very good at maths. But this seems easy :D. I'm still a beginner, but please give me points.

You have $55,000 in savings account that pays 2% intrest per year. The inflation rate that year is 3.24%. How much do you make i
Sever21 [200]
Your interest formula is given to you.

Interest in a year = principal (the amount invested) * rate (the interest rate) * period (the time you're measuring)

Interest = 55,000 * 2% * 1 year = 55,000 * 0.02 * 1 = $1,100

How much would you need to have made for your spending power to keep with inflation? Your interest rate would have needed to match the inflation rate, otherwise prices are going up faster than you're saving.

Required interest = 55,000 * 3.24% * 1 year = 55,000 * 0.0324 * 1 = $1,782

How much buying power did you lose? The difference between your required interest and your actual interest.
Buying power lost = 1,782 - 1,100 = $682. You lost this much in buying power.

Hope that helped :)
