First, don't freak out! :). I'll help!
11) cost per day plus the cost per pastry times the # of pastries is less than or equal to 500.
p= # of pastries
119+2.25p<=500
subtract 119 from both sides
2.25p<=381
divide both sides by 2.25
p<=169.33
Answer: C) 119+2.25p<=500; p<169
12) Add the two numbers together.
-1.56 + 0.73= -0.83
Answer: D) -0.83 pounds
13) t= cost per ticket
$ spent at concession plus 5 tickets times the cost of the tickets (t) equals the total.
$29.25 + 5t= $55.50
subtract 29.25 from both sides
5t= 26.25
divide both sides by 5
t= $5.25 price of each ticket
Answer: C) 29.25 + 5t=55.50; t=$5.25
Hope this helps! Good luck! :)
