Question

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.)

Answer 1

They invested total $2730 over the past two years.

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.

`\$25* (10)/(100)=\$2.5`

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.
