Since there is a 5 to the right of the decimal, you will round the number immediately to the left of the decimal up. So the nearest whole number would be 71.
Ok so first, write down the equation. We know that x=3 and y=4. You just basically plug in the terms into the variables. So it would be 3(3)+1/4(4)^2. Simplify that equation and you should get your answer :)
we use the interest formula. 4000*1.03^11=1.38423387*4000=5536.93548, or 5536.94.
