Answer provided by our tutors
let
b = the number of bags of jelly beans bought
d = the number of bags of lemon drops bought
Mrs. Tully bought 4 more bags of jelly beans selling at 35 cents a bag than of lemon drops selling at 45 cents a bag
b = d + 4
she spent $3 for the candy or in cents that is 300 cents
the money spent on jelly beans + the money spent on lemon drops = the total money spent that is 300 cents
35b + 45d = 300 divide both sides by 5
7b + 9d = 60
by solving the system of equations
b = d + 4
7b + 9d = 60
we find
b = 6 bags
d = 2 bags
