To the nearest cent, how much will he have in 2 years?

Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

$86.25

Step-by-step explanation:

For this problem, we are given p, r, t.

p=70 (starting amount)

r=0.11 (11%)

t=2 (years)

We can plug this into the equation B=p(1+r)^t

B=70(1+0.11)^2

B=86.247

Sam would have $86.25

$86.25

Step-by-step explanation:

B = p(1 + r)t must be written as B = p(1 + r)^t.  The "^t" denotes exponentiation.

Then, with B = p(1 + r)^t, we need to insert $70 for p, 0.11 for r and 2 for t:

B = $70(1 + 0.11)^2  =  $86.25

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
