Haley invests $16,820 in a nine-year CD bearing 5.8% interest, and $21,950 in an online savings account giving 3.0% interest. Wh
a_sh-v [17]

Answer:

$2853.5

Step-by-step explanation:

Let us assume that the interest rate of both the investments of Haley is simple interest.

So, $16820 amounts of investment in nine-year CD bearing 5.8% interest will get interest of 16820 \times \frac{5.8}{100} \times 9 = 8780 dollars.

Again, $21950 amounts of investment in an online savings account giving 3% interest will give interest of 21950 \times \frac{3}{100} \times 9 = 5926.5 dollars.

Therefore, the nine-year CD will give more interest by $(8780 - 5926.5) = $2853.5. (Answer)
