Larry invests $100 in a savings plan. The plan pays 4 1/2 % interest each year on his $100 account balance.

a. How much money will Larry earn in interest after 3 years? After 5 years?

b. How can you find the balance of Larry’s account at the end of 5 years

a) Write an Equation

f(t) = 100(1.045)^t  ** t = time; f(t) = money in savings account

Solve for 3 years

100(1.045)^3 = 100(1.141166125)

Simplify

114.1166125 dollars, which rounds to $114.12

You subtract the original amount of money, to find the interest, and get

$14.12

Solve for 5 years

100(1.045)^5 = 100(1.24618193765)

Simplify

124.618193765 dollars, which rounds to $124.62

You subtract the original amount of money, to find the interest, and get

$24.62

b)

To solve for 5 years:

100(1.045)^5 = 100(1.24618193765)

Simplify

124.618193765 dollars, which rounds to $124.62

**Note: I assumed that this is compounded interest, not simple interest

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
