If Ava waters her lemon tree 12 times, then she has used 10.667 gallons of water.
<u>Solution:</u>
Given that , Ava uses 
gallons of water every time she waters her lemon tree.
If she waters her lemon tree 12 times, we have to find how much water will she use
Total water used = water used for 1 time 
number of time water used for plants
Here water used for one time = 
Number of time watered = 12
Hence, Ava used 10.667 gallons of water.
By the looks of it, B can be eliminated because obviously GRAM isn't plotted correctly. C is eliminated because it looks exactly like GRAM its only reflected. Its A since the coordinates have to go right 11 units and 2 units up.

Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
Let r and s represent the number of times Caleb can ride the roller coaster and watch a show, respectively. The time Caleb needs to allow for each roller coaster ride is (wait time) + (ride time) = (30 +5) min = 35 min. Then we can write the equations
r - s = 3
35r +25s ≤ 345
Adding 25 times the first equation to the second, we get
25(r -s) +(35r +25s) ≤ 25(3) +(345)
60r ≤ 420 . . . . . . collect terms
r ≤ 7 . . . . . . . . . . . divide by 60
Caleb can ride a maximum of 7 roller coasters and watch 4 shows in 345 minutes.

The problem can obviously be worked using two equations instead of one equation and an inequality. It isn't clear until the final answer that the number of minutes comes out exactly the amount needed, which is why we chose an inequality.
