If I have 18 dimes and quarters that are worth $2.25, which system would represent this?

• d + q = 2.25
  .10d + .25q = 18
  

• d + q = 18
  .10d + .25q = 2.25

• 18 d = q
  .10d + .25q = 2.25

• d+ q = 18
  .25d + .10q = 2.25

What is the system for the two rental cars? Car A cost $28 per day plus insurance of $15 and Car B cost $23 per day plus insurance of $18.

• y = 28x + 15
  y = 23x + 18

• y = 28x + 18
  y = 23x +15

• y= 15x + 28
  y = 18x + 23

• 28x + 23 y = 15
  28x + 23y = 18
