Question

Someone, please help me

Answer 1

Answer:

≈ $937

Step-by-step explanation:

to answer this, we have to use the compound interest formula which is:

A = P(1 + r/n)^nt

the meanings of each variable are:

A = result

P = principal amount

r = rate (in decimal form)

n = the number of compound periods (eg: annually, quarterly, etc)

t = time

in the word problem, we need to solve for A. we are given P, r, n, and t.

P = 800

r = 0.02 also known as 2%

n = 1 keyword being annually which is equal to the value of 1

t = 8

we can plug these values into the formula:

A = 800(1 + 0.02/1)$^(^1^)^(^8^)$

we can use a calculator to calculate this easier but ill break it down:

A = 800(1 + 0.02/1)$^8$

A = 800(1.02)$^8$

A = 800(1.02)$^8$

A = 800(1.17165938)

A ≈ 937.327

we can round 937.327 to the nearest dollar which is $937
