garri49 [273]

Answer:

£21552.

Step-by-step explanation:

Given information:

Principal amount = £18790

Rate of simple interest =4.9% = 0.049 per year

Time = 3 years

Formula for simple interest:

$I=P\times r\times t$

where, P is principal, r is rate of interest and t is time in years.

$I=18790\times 0.049\times 3$

$I=2762.13$

Total amount after 3 year is

$A=P+I$

$A=18790+2762.13$

$A=21552.13$

$A\approx 21552$

Therefore, Dan have £21552 after 3 years.

4x=32

x=8

y=13

9)

do the same here

x=y+1

2y+x=19

2y+y+1=19

3y=18

x=6
