Q:
# The combined yearly interest for x dollars invested at 12% and 45,000−x dollars invested at 8% is ________.

Accepted Solution

A:

.12x + .08(45000-x)

.12x + 3600 - .08x

.12x - .08x + 3600

.04x + 3600

combined yearly interest = .04x + 3600

.12x + 3600 - .08x

.12x - .08x + 3600

.04x + 3600

combined yearly interest = .04x + 3600
