"X is partly constant and partly varies as y"

---> x = ky + p

when y=2,x=30 ---> 30 = 2k + p

when y=6,x=50 ---> 50 = 6k + p

subtract: 20 = 4k

k = 5

sub back in the first: 30 = 10+p

p = 20

x = 5y + 20

now you can answer B

notice this is just a variation of y = mx + b

guajiro [1.7K]
We have to calculate the amount of money Peter will have in his account after 5 years. Formula for the amount after t years with interest compounded continuously : A = P * e ^(rt)
We know that r = 0.06, t=5, e = 2.71 and p= $8,000 
A = 8,000 * 2,718 ^(0.06 * 5) = 8,000 * 2,718 ^ (0.3) = 8,000 * 1.3488158  = 10,798.53 so the answer is 10,798.53
