Answer:
$75
Step-by-step explanation:
To find out how much George's mom paid for the 6 tickets, first find the unit rate, that is cost per ticket.
The unit rate/constant of proportionality between cost of tickets (y) and number of tickets (x) can be calculated using the coordinates of any points on the graph.
Using (4, 50), this means that 4 tickets cost $50.
Unit rate/constant of proportionality = y/x = 50/4 = 12.5
This means a ticket costs $12.5.
Therefore, 6 tickets would cost:
6 tickets × $12.5 = $75.
George's mom paid $75 for the tickets?
I believe the answer for the first question is A. but not 100% sure, it's the only one I can figure out to be right.
The answer for the second question is C. 90% of 30 is 27.
I hope this helps.
Based on the given details above, here are the answers to your question.
If x represents the number of quarters in the jar, the equation that can be used to find the number of quarters is this <span>0.25x + 0.05(150 x) = 28.30.
