Morgan invested $4,200 into two accounts. One account paid 4% interest and the other paid 7.5% interest. She earned 7% interest
Lana71 [14]

Answer:

The amount invested at 4% was $600

The amount invested at 7.5%  was $3,600

Step-by-step explanation:

Let

x ----> the amount invested at 4%

$4,200-x -----> amount invested at 7.5%

we know that

The total interest earned is equal to the interest earned by the amount invested at 4% plus the interest earned by the amount invested at 7.5%

Remember that

4\%=4/100=0.04

7.5\%=7.5/100=0.075

7\%=7/100=0.07

so

The linear equation that represent this situation is

0.04x+0.075(4,200-x)=0.07(4,200)

Solve for x

0.04x+315-0.075x=294

0.075x-0.04x=315-294

0.035x=21

x=\$600

\$4,200-x=\$3,600

therefore

The amount invested at 4% was $600

The amount invested at 7.5%  was $3,600
