The answer is in the image
SI=(P*R*T)/100
P=2000
R=1.5
T=6
SI=(2000*1.5*6)/100
=(2000*9)/100
=180
Neil will earn interest of 180
The total nom of code that can be used is equal to 5+3 = 8
The solution is in the following image
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
Here,
tip=18%of $32
tip=(18/100)*32
=0.18*32
=$5.76
Total payment=32+5.76=$37.76
Speed=Distance/time
distance=15m
time=1sec
speed=15/1=15m/sec
Distance=Speed*time
time=15min=15*60sec=900sec
Distance travelled in 15 min=15*900=13,500m
=13500/1000 km=13.5Km
