CD $ 70,000

Mutual fund $ 10,000

maximum return $ 6,200

Explanation:

we want to maximize return considering the following restrain

mutual fund > 10,000

certificate of deposit = > 2mutual fund

CD + Mutual Fund = 80,000

as the certificate yield is higher than mutual we will invest the minimum in mutual and the rest in the CD which will fullfil the requirement of at least twice as much invested in CD.

return = CD x 0.08 + mutual x 0.06

return = (80,000 - 10,000) x 0.08 + 10,000 x 0.06

return = 5,600 + 600 = 6,200
