Jane wants to save money to buy a motorcycle. She invests in an ordinary annuity that earns 4.2% interest, compounded quarterly.

Sauron [17]

Answer:

she need to pay is $550.40

Step-by-step explanation:

given data

interest = 4.2 % compounded quarterly = 0.042 / 4 = 0.0105

future value = $7000

time = 3 year = 3 × 4 = 12 months

to find out

How much money she need to pay

solution

we will apply here formula for future value for compound quarterly

that is

future value = principal × $\frac{(1+r)^{t} -1 }{r}$ .............1

put here all these value

future value = principal × $\frac{(1+r)^{t} -1 }{r}$

7000 = principal × $\frac{(1+0.0105)^{12} -1 }{0.0105}$

principal = 550.40

so she need to pay is $550.40

question is ,four children saved £29 to go on a coach. They each saved the same amount. How much did each saved

Andreas93 [3]

If they saved £29 all together, and if each of them saved the same amount,
then each saved £29/4 = £7.25 or £7 and 25p.

(Before decimalization in 1971, £7.25 would have been £7 and 5s .)
