Question

a jeweler bought some necklaces and bracelets for $1,100. the cost of the necklaces was 20% more than the cost of the bracelets. how much did the jeweler pay for
A) the necklaces?
B) the bracelets?

Answer 1

x is the cost of the necklaces, y is the cost of the bracelets.
x + y = 1100
x = 1.2y
1.2y + y = 1100
2.2y = 1100
y = 500
x =600
