How many years, to the nearest tenth would it take for an investment of $100 to double if it is earning a continuous compound interest of 3.5% per year? (A) 17.4 years (B) 19.8 years (C) 22.5 years (D) 25.1 years​

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

seven students earned $833 by shoveling snow. if they share the money equally, how much money will each student get

answer: each student earns $119

step-by-step explanation:

to find the answer you have to divide 833/7 which is 119

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
