Mrs. ming invested an amount of money in two accounts for one year. she invested some at 8% interest and the rest at 6% interest. her total amount invested was $1,500. at the end of the year, she had earned $106.40 in interest. how much had mrs. ming invested in the account paying 6%? $117 $680 $760 $820

The correct option is B) $680.

Step-by-step explanation:

Consider the provided information.

Her total amount invested was $1,500. At the end of the year, she had earned $106.40 in interest.

Let she invested x amount with 8% interest rate.

Total amount she invested was $1,500, thus the amount she invested with 6% interest rate was 1500-x.

Total interest she earn was $106.40

Write this information into mathematical form.

Hence, she invested $820 with 8% interest rate.

The amount she invested with 6% interest rate was 1500-x.

Substitute the value of x in above.

1500-820=680

Hence, she invested $680 with 6% interest rate.

The correct option is B) $680.
