j: cost of one pair of jeans

Yesny had $240 to spend on five pairs of jeans. How much did each pair of jeans cost if she has $10 left?

•  $5j-10=240$ 

•  $5-10j=240$ 

•  $5j+10=240$ 

•  $5+10j=240$ 

c: the cost of one ice cream cone

I bought 3 ice cream cones and paid $9. How would I write this equation?

•  $9c+3=9$  

•  $3c+9=0$  

•  $3c=9$  

•  $3c=-9$

Justin spent $50 on 2 pairs of jeans and 1 pair of socks. The jeans were $23 each. How much did the pair of socks cost?s: cost of the pair of socks

•  $23\left(2\right)+s=50$  

•  $23\left(1\right)+s=50$  

•  $50+23=2s$  

•  $23-50=2s$
