Gunther invested $10,000 in two mutual funds. one of the fun rose 6% in one year, and the other rose 9% in one year. if gunther's investment rose a total of $684 in one year how much did he invest in each mutual fund.

The amount invested at 6% was $7,200 and the amount invested at 9% was $2,800

Step-by-step explanation:

Let

x ----> the amount invested at 6%

10,000-x -----> the amount invested at 9%

we know that

The interest earned in one year by the amount invested at 6% plus the interest earned by the amount invested at 9% must be equal to $684

Remember that

so  

The linear equation that represent this problem is

solve for x

therefore

The amount invested at 6% was $7,200 and the amount invested at 9% was $2,800

if i put something wrong your not gonna like it so rather not say nothing.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
