Writing system of equation

Your family goes to a southern style restaurant for dinner. There are 6 total people in your family. Some order chicken for $14 and the rest order steak for $17. The total bill is $99. Write a system that could represent this situation.

• c + s = 6
  14c + 17s = 99
• c + s = 99
  14c + 17s = 6
• c + s = 6
  17c + 14s = 99
• c + s = 99
  17c + 14s = 6

Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of color brochures, which cost a total of $134. After those ran out, Christian spent $120 on 3 boxes of black-and-white brochures and 3 boxes of color brochures. Let x represent the number of black and white brochures and let y represent the number of color brochures, which system represents this situation?

• x+y=134

  x+y=120

• 3x+3y=134

  4x+3y=120

• 4x+3y=134

  3x+3y=120

• 7xy=134

  6xy=120

Homer sells tickets for admission to your school play and collects a total of $104. Admission prices are $6 for adults and $4 for children. He sold 21 tickets total. Write a system to represent this situation assuming "a" represents # of adult tickets and "c" represents # of children's tickets.

• a + c = 21
  6a + 4c = 104
• a + c = 104
  6a + 4c = 21
• a + c = 21
  6c + 4a = 104
• a + c = 104
  6c + 4a = 21

At Barnes and Noble, Maria bought a book and a CD that cost a total of $33. If the price of the book is $6 less than twice the cost of the CD, which system of equations matches the situation?

• b + c = 33

  b = 6 - 2c

• b + c = 33

  b = 2c - 6

• b + c = 33

  c = 2b - 6

• b + c = 33

  c = 6 - 2b

A pizza buffet restaurant has one price for adults and other price for children under age twelve. Tim's family has two adults and three children. Their bill was $40.50. Amy's family has three adults and one child. Their bill was $38. Which system of equations could be used to determine the buffet price for an adult and the price for a child?

• a+ c = 40.50

  a + c= 38

• 2a + 3c = 40.50

  3a + c = 38

• 2a + c = 40.50

  3a + 3c = 38

• 2a + 3c = 38

  3a + c = 40.50
