If Jimmy invests $250 twice a year at 4% compounded semi-annually, how much will his investment be worth after 3 years?

with step by step

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

the answer is d

step-by-step explanation:

answer: (3,11) is your answer.
