Answer:
<h2>
<u>$52.5</u></h2>
Step-by-step explanation:
Step one:
given data
we are given that the linear function for the cost is c=3.5t
c is the cost and
t is the number of tickets.
We are told that t=15, to find c, let us put the value of t in the linear function for the cost
<u>This shows that 15 tickets will cost $52.5</u>

Hey there! :)
All you have to do is divide the numerator(top number) by the denominator(bottom number).
17 ÷ 8 = 2.125
Rounded to the nearest hundredth = 2 places after the decimal point.
After the 2 is a 5. If it's 5 or greater, you move it up by 1.
2 + 1 = 3
2.125 = 2.13
Your answer is A ⇒ 2.13
Hope this helps :)
Answer:
3 cars
Step-by-step explanation:
If 12 cars are needed to carry 36 students,
<em>12</em><em>c</em><em>a</em><em>r</em><em>s</em><em> = 36</em>
the number of cars to carry 9 students will be:
xcars = 9
cross the two equations
36x = 12 X 9
36x = 108
x = 108/36
x= 3
Therefore, 3 cars are needed to carry 9 students
OR
12 cars will carry 36 students
so 1 car will carry, (36/12)students
therefore, 1 car will carry 3 students
So, for 9 students,
9students = 9/3 = 3
