Answer 1

Step-by-step explanation:

let cost of bats be x

let cost of ball be y

3x+6y=3900

x+3y=1300 eq 2

3(X+2y)=3900

x+2y=1300. EQ 1

x+2y=1300

y=1300-x

---------------

2

x=50

1300-50 =1250/2= 625

x=100

y=1300-100=1200/2=600

x=200

y=1300-200=1100/2=550

(I) 50,625

(ii) 100,600

(iii) 200,550

x+3y=1300

y=1300-x

----------------

3

x=70

y=1300-70=1230/3=410

x=100

y=1300-100=1200/3=400

x=130

y=1300-130=1170/3=390

(I) 70,410

(ii) 100,400

(iii) 130,390
