the cost of a five star is $5
she can buy 50 Chacobar or 40 Fivestar.
then, cost of 50 Chacobar=cost of 40 Fivestar
=》cost of 40 Fivestar=40×20=200
=》cost of 50 Chacobar=200
=》cost of each Chacobar=200/50=4
She uses 10% amount for petrol=》10% (200)=$20
remaining balance =200-20=$180
cost of 20 Fivestar =20×5=$100
remaining balance=180-100=$80
she purchases some Chacobar. be x say,
=》4(x)=80
=》x=80/4
=》x=20
therefore, the number of Chacobar she can buy =20
