Ocean Beach Financial Planning Offers Three Types of Investments: Low-Risk

Ocean Beach Financial Planning offers three types of investments: low-risk, medium-risk, and high-risk. A customer decides to invest $4,700 and is given three options for investing in the three funds. Determine the interest rate percentage for the low-risk, l, medium-risk, m, and high-risk, h, investments based on the interest earned for each option in the first year.
$100l + $1300m +$3300h = $359.00
$550l + $1700m +$2450h = $337.00
