Jenny invests $20,000 in an account earning 4.5% interest, compounded annually. Cam invests $20,000 in an account earning 6.5% interest, compounded annually. Given that no additional deposits are made, compare the balances of the two accounts after 5 years. (round to the nearest dollar)
A) Cam has $2,082 more in his account than Jenny.
B) Jenny has $2,082 more in her account than Cam.
C) Cam has $2,478 more in his account than Jenny.
D) Jenny has $2,478 more in her account than Cam.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
