Joseph has $10,500 to invest. He initially chose a simple annual interest rate of 5%
for four years, but decided to consider
other options. Which of the following
changes will increase the interest he
earns the most?
F Simple interest, 4.75%, 4.5 years
G Simple interest, 5.25 %, 4 years
H Simple interest, 5%, 4.25 years
3 Compound interest, 5%, 4 years

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
