Cheryl spent $45 for three scarves and a bracelet. She knows that the cost of the bracelet was $15, and the scarves were all the same price. She wants to know the cost of each scarf. Cheryl knows that three times a number plus $15 is $45. Choose the equation that will give the cost of each scarf. Solve for x.

• 15 + 15 + 15 + x = 45

  
  

  x = 10

• 45 - 15 = x

  
  

  x = 10

• 3x + 15 = 45

  
  

  x = 10
