The amount invested in certificate of deposit paying at 8% was $6,000 and the amount invested  in a savings account at 9% was $3,000

Step-by-step explanation:

The question in English is

Vanessa wants to invest $9,000. She invests part in certificate of deposit paying at 8% and  the rest in a savings account at 9% per year. If the interest earned in one year was $750,  How much did you invest in each one?

Let

x -----> the amount invested in certificate of deposit paying at 8%

(9,000-x) -----> the amount invested  in a savings account at 9% per year

Remember that

we know that

Solve for x

therefore

The amount invested in certificate of deposit paying at 8% was $6,000 and the amount invested  in a savings account at 9% was $3,000

c is the final : )
