Suppose you buy a CD for $300 that earns 3% APR and is compounded quarterly. The CD matures in 3 years. How much will this CD be
andrew-mc [135]

Given: Principal Amount (P) = $300

The rate of interest (r) = (3/4) compounded quarterly.

No. quarters in 3 years (n) = 3×4 = 12

To find: The amount for the CD on maturity. Let it will be (A)

Formula: Compound Amount (A) = P [ 1 + (r ÷100)]ⁿ

Now,   (A) = P [ 1 + (r ÷100)]ⁿ

or,            = $300 [ 1 + (3 ÷400)]¹²

or,            = $300 × [ 403 ÷ 400]¹²

or,            = $300 × 1.0938069

or,            = $ 328.14

Hence, the correct option will be C. $328.14

I=$26.24, P=$500, T=18 months the annual interest rate is
NeX [460]
A = $2,861.60

I = A - P = $2,361.60

Equation:
A = P(1 + rt)

Calculation:
First, converting R percent to r a decimal
r = R/100 = 26.24%/100 = 0.2624 per year.

Solving our equation:
A = 500(1 + (0.2624 × 18)) = 2861.6
A = $2,861.60

The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 26.24% per year for 18 years is $2,861.60.

A roofer sketches a diagram of a house on which he is working.
docker41 [41]
Using the SSA formula:

X = SQRT ( 40^2 + 26^2 - 2*40*26*cos(65))

X = SQRT(2276 - 2080*cos(65))

X = SQRT(1396.954)

X = 37.37 = 37.4 ft.
