Answer:

The balance in Tom's account is = $ 2265.41

Step-by-step explanation:

Principal amount = $ 2000

Rate = 2.5 %

Time = 5 years

Since Amount is compounded quarterly so

New rate of interest = \frac{2.5}{4} = 0.625

Time = 5 × 4 = 20 years

Now the amount in the account is given by

A = P (1+\frac{R}{100}  )^{T}

A = 2000 (1+\frac{0.625}{100}  )^{20}

A = $ 2265.41

Therefore the balance in Tom's account is = $ 2265.41

Sidana [21]

Answer: $2250

Step-by-step explanation:

<u>Given information</u>

Dimension of the room = 20 feet × 15 feet

Cost of tiles = $7.50 / ft²

<u>Derived formula from the given information</u>

Total cost = Floor area × Cost of tiles

<u>Substitute values into the formula</u>

Total cost = Floor area × Cost of tiles

Total cost = (20 × 15) × (7.5)

<u>Simplify by multiplication</u>

Total cost = 300 × (7.5)

\Large\boxed{Total~cost~=~2250~Dollars}

Hope this helps!! :)

jolli1 [7]
Use the attached formula.
exp = [log (total / principal) / n*years]
where "n" is compounding periods per year
exp = [log (7,194.66 / 2,978.41) / (365*21)
exp = log ( <span> <span> <span> 2.4156042989 </span> </span> </span> ) / 7,665
exp = log ( <span> <span> 2.4156042989 </span> </span> ) / 7,665
exp = 0.38302579382 / 7,665
exp = <span> <span> <span> 0.00004997074935681670 </span> </span> </span>

rate = (10^exp -1)* n
rate = (10^<span>0.00004997074935681670 -1) * n
</span>rate = <span><span>(1.0001150685 </span> -1) * 365
</span>rate = <span>(.0001150685) * 365</span>
rate = <span> <span> <span> 0.0420000025 </span> </span> </span>
rate = <span>4.20000025 %
rate = 4.2 %

Yes, it's just that easy.  LOL
