Victor has $40 in a savings account. The interest rate is 5%, compounded annually.
To the nearest cent, how much interest will he earn in 3 years?

$6.31

Step-by-step explanation:

We are going to use the compound simple interest formula for this problem:

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

Our first step is to change 5% into its decimal form:

5% -> -> 0.05

Next, plug in the values:

Lastly, subtract 40 (our original value) from 46.31:

Victor earned $6.31 in interest after 3 years.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

step-by-step explanation:

your victory is right around the corner. never give up.
