Jojo, Ben and Martin are running a relay race. Jojo ran her part in 7.89 seconds, Ben ran his part in 10.217 seconds and Martin ran his part in 9.028 seconds. What was their team's total time?
Their team's total time is the sum of the three individual times:
7.89 seconds + 10.217 seconds + 9.028 seconds = <<7.89+10.217+9.028=27.135>>27.135 seconds. Answer: \boxed{27.135}.
Sally went to the mini-mart and spent $34.29. If she bought 9 package or Oreos, how much was each pack of Oreos?
To find out how much each pack of Oreos cost, we need to divide the total amount spent ($34.29) by the number of packs bought (9):
$34.29 / 9 = $<<34.29/9=3.81>>3.81.
Therefore, each pack of Oreos cost $3.81. Answer: \boxed{3.81}.
