Maggie has $14,100 to invest, and wishes to gain $4,000 in interest over the next eight years. Approximately what is the minimum simple interest rate Maggie needs to reach her goal?

Answers

Given:
Principal: 14,100
Interest:4,000
term: 8 years
rate: ?

We'll use the simple interest rate formula to get the interest rate needed.

Simple Interest = Principal * Interest Rate * Term
4,000 = 14,100 * Interest rate * 8 years
4,000 = 112,800 * Interest rate
4,000 / 112,800 = Interest rate
0.03546 = Interest rate

0.03546 * 100% = 3.546% or 3.55% is the interest rate needed.

S.I = 14,100 * 0.0355 * 8
S.I = 500.55 * 8
S.I = 4,004.40

A tree that is 3 feet tall is growing at a rate of 1 ft per year. A 5 ft tree is growing at a rate of 0.75 ft per year.The ordered pair (t, h)(t, h) represents the time, t, at height, h.

Which ordered pair represents the year when the trees will be the same height?

Answers

The given can be represented by equations
A tree that is 3 feet tall is growing at a rate of 1 ft per year
h = t + 3  
A 5 ft tree is growing at a rate of 0.75 ft per year
 h = 0.75t + 5  
Equating the two equations  
t + 3 = 0.75t + 5
 t = 8 yrs
 h = 8 + 3
 h = 11 ft  
(8,11)

it will be at (8,11).
