2. How much interest is earned by investing $2100 for three years at 4.5% compounded
monthly?

The final balance is $2,402.92.

The total compound interest is $302.92.

Step-by-step explanation:

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

A=final amount

P=initial principal balance

r=interest rate

n=number of times interest applied per time period

t=number of time periods elapsed

A=2100(1+.045/12)^(3*12)

A=2100(1.00375)^(36)

A=2100*1.442478322

A=2402.92

gain of 302.92

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
