<span>A.
write an expression for the total cost of the three types of tickets. </span>
<span>adults
cost:$8.75
childrens cost:$6.50
senior citizen cost:$6.50 </span>
so from the given data, the expression for the total cost
at the movie 16 theater
<span>total cost = 8.75a + 6.50a + 6.50s</span>
Answer:
Step-by-step explanation:
12A+8W > 343 represents the number of minutes the robot filters air A and water W to filter more than 343 liters of air and water.
If the robot filters air for 20 minutes and water for 15 minutes, plugging A as 20 and W as 15, let us check if the equation is true or not.
Checking left side:
12A + 8W = 12(20) +8(15)
240+ 120 = 360
Checking right side: 343
12A+8W > 343
360>343
True.
So the robot meets the first expectation.
Let us check for second equation:
3A+4W < 49
Left side : 3A +4W = 3(20) +4(15) = 60 +60 =120
Right side is 49
comparing left and right side:
3A+4W < 49
120<49
False.
So the robot does not meet the second expectation.
