Wendy had 35 coins in pennies and nickels.  She had $1.03.  Which system of equations could be used to determine the  number of coins she has?

• .01p + .05n = 35
  p + n = 103
• 1p + 5n = 1.03
  p + n = 35
• .01p + .05n = 1.03
  p + n = 35
• .05p + .01n = 1.03
  p + n = 35

At a holiday ski resort, skis cost $16 to rent and snowboards cost $19. If 28 people rented on a certain day and the resort brought in $478, which system could be used to determine the number of skis (s) and snowboards (b) rented?

• s+b=478
  19s+16b=28
• s + b = 28
  16s+19b=478
• s+b=478
  16s+19b=28
• s+b=28
  19s+16b=478

A sporting goods store sells left handed (x) and right handed (y) gloves. In one month, 12 gloves were sold for a total of $561. Right handed gloves cost $45 each and left handed gloves cost $52. Which system could be solved to determine the number of each type of glove sold?

• x + y = 561
  45x+52y=12
• x + y = 12
  52x+45y=561
• x + y = 12
  45x+52y=561
• x + y = 561
  52x+45y=12

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
