5. last year, dan and paula regularly invested $25/week in a mutual fund account. this

year, they increased their weekly investment by 10 percent. what amount did they invest

in the account over the past two years? (hint: there are 52 weeks in a year.)

They invested total $2730 over the past two years.

Step-by-step explanation:

Consider the provided information.

Dan and Paula regularly invested $25/week in a mutual fund account.

There are 52 weeks in a year.

Total money they invested in a mutual fund in first year.

$25×52 = $1300

They increased their weekly investment by 10 percent.

First find the 10% or 25.

That means they invest $25+$2.5 = $27.5

They invest $27.5/week in next year.

Total money they invested in a mutual fund in second year.

$27.5×52 = $1430

Hence the total money they invested in the account over the past two year is:

$1300+$1430=$2730

Hence, they invested total $2730 over the past two years.

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
