A local charity is holding a fun run for a fundraiser. They spent $400 on t-shirts to give to runners. The equation shown can be used to find the total money raised, y, if x number of runners paid the entrance fee for the run. y = 25x - 400 What does the 25 represent in the equation?

• the number of runners

• the price per entrance fee

• the cost of the t-shirts

• the number of runners

Dennis mowed his next door neighbor’s lawn for a handful of dimes and nickels, 80 coins in all.  Upon completing the job he counted out the coins and it came to $6.60.  Which system of equations could be used to find the exact number of dimes and nickels? 

• d + n = 6.60
  .10d + .05n = 80

• d + n = 80
  d + n = 6.60

• d + n = 80
  .10d + .05n = 6.60

• d + n = 80
  .05d + .10n = 6.60
