Question

Li and Jen went shopping

. Li bought 4 pairs of earrings and 1 necklace for a total of $54.
• Jen bought 1 pair of earrings and 3 necklaces for a total of $52
Each pair of earrings cost e dollars and each necklace cost n dollars Which system of equations can be used to find the cost in
dollars, of each pair of earings and each necklace?

Answer 1

earrings cost $10

necklaces cost $14

we can find this out by using elimination

your equations would be

4x+y=54

x+3y=52

then we would multiply the second equation by -4 and eliminate the x's and solve for y (which would be 14)

then we can plug in y to the first equation (4x+y=54) and get 10 for x

*x=earrings and y=necklaces*

hope this helps! :)
