Adream club charges $60 for the first month of membership, and $2 less each month after that. (yes, after a while the dream club starts paying money to members instead of charging them : what is the total membership for a year? for 5 years?

Total membership for a year is $588

Total membership for 5 years is $60

Step-by-step explanation:

This is an arithmetic sequence of the form:

60, 58, 56, 54 ...

The first term is a = 60

the common difference is d = -2

We need to find the total member cost for a year, that is the sum of all the first 12 terms. We use the formula of sum of arithmetic sequence shown below:

Where

a is first term

n is the number of term [here, 12]

d is common difference

From what we know, we can find:

Total membership for a year is $588

Now to find this for 5 years, we have to find 5*12 = 60 months.

So S_60, formula and find:

Total membership for 5 years is $60

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
