Answer:
a) 180%;
b) 5.

Explanation:
a) Purchase price per coat = 55;
Sales price per coat = 99.
% of purchase price is sales price :
X%*55 = 99;
(x/100)*55 = 99;
0.01x*55 = 99;
0.55x = 99;
x = 99/0.55;
x = 180.
180% of purchase price.
b) 180% * 45 = 81 per jacket.
Number of jackets to sell to make atleast $390 in sales
$390 / $81 = 4.8.
Hence, 5 jackets.

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

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
