a= €3700

b=3.8%

Step-by-step explanation:

the difference between 2006 and 2018 =12 years 12× 2%=24%

24%×30000=3720

3700 to nearest €100

2, 95000_ 80000= 15000

5 years = 15000

year= 3000

what percentage of 80000( not 95000) = 3000

3000÷8000×100%=30÷8

3.75

3.8% to 2 significant figures

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
