2508

Step-by-step explanation:

We are given that

Principal ,P=2200

Rate of interest, r=7%

Time, t=2 year

We have to find the final account balance after two years.

$S.I=\frac{P\times r\times t}{100}$

Using the formula

$S.I=\frac{2200\times 7\times 2}{100}=308$

Amount=P+S.I

Amount=2200+308

Amount=2508

Hence, the final account balance after two years=2508

Part 1: you and your best friend want to take a vacation to australia. you have done some research and discovered that it will cost $2500 for the plane tickets, all-inclusive hotel and resort, and souvenirs. you have already saved $2200. if you invest this money in a savings account with a 1.55% interest rate compounded annually, how long will it take to earn enough money to go on the trip? use the compound interest formula a = p (1 + i)n, where a is the accumulated amount, p is the principal, i is the interest rate per year, and n is the number

Part 1) $8.3\ years$

Part 2) $\$2,424.27$

Part 3) $\$2,266.02$

Part 4) In the procedure

Step-by-step explanation:

Part 1) we know that

The compound interest formula is equal to

$A=P(1+i)^{n}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

i is the interest rate in decimal

n is number of years

n is the number of times interest is compounded per year

in this problem we have

$P=\$2,200\\ A=\$2,500\\ r=0.0155\\n=?$

substitute in the formula above

$\$2,500=\$2,200(1+0.0155)^{n}$

$(2,500/2,200)=(1.0155)^{n}$

Applying log both sides

log(2,500/2,200)=(n)log(1.0155)

n=log(2,500/2,200)/log(1.0155)

$n=8.3\ years$

Part 2)

in this problem we have

$P=?\\ A=\$2,500\\ r=0.0155\\n=2\ years$

substitute in the formula above

$\$2,500=P(1+0.0155)^{2}$

$\$2,500=P(1.0155)^{2}$

$P=\$2,500/(1.0155)^{2}$

$P=\$2,424.27$

Part 3) in this problem we have

$P=\$2,000\\ r=0.018\\n=7\ years$

substitute in the formula above

$P=\$2,000(1+0.018)^{7}=\$2,266.02$

The money is not enough

Part 4)

I would personally increase the investment from 2,200 dollars so that it grows to 2,500 dollars at the time I want to make the trip, for example if I wanted to make the trip in two years, I would increase the initial investment from 2200 dollars to 2427 dollars.

Step-by-step explanation:

PART 1:

you have 2,200 and interest is 1.55%

A = 2200(1+0.0155)1 A = 2,234.10

A = 2200(1+0.0155)10 A = 2,565.80

A = 2200(1+0.0155)9 A = 2,526.63

A = 2200(1+0.0155)8 A = 2,488.07

9 Years with $2,526.63

PART 2:

A = 2425(1+0.0155)2 A = 2,500.76

You need to invest $2,425.00

PART 3:

A = 2000(1+0.018)7 A = 2,266.02

You have $2,266.02 which is underbudget

PART 4:

Personally, I would add to the investment of $2,200 so that it will grow to $2,500 faster. If I waited for just the $2,200 to grow alone it would take 9 years and if I'm looking at a trip now I would like to go sooner. So if I keep adding to the original $2,200 overtime it will collect interest faster and I would be able to take the trip sooner. I justify my answer with PART 2.

You can buy jars of the same jam in 2 sizes large jar:440g for £1.54 small jar:340g for £1.26 By considering the price per gram, work out which jar is the best value for money. Working must be shown

Step-by-step answer

P Answered by PhD

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
