Answer:
The regular price of the ticket was $12.
Step-by-step explanation:
Let us call
the regular price of the tickets, and if she had bought tickets at this price, the total cost would have been
.
But Holly got $4 off the regular ticket price, that means one ticket cost her
and if she bought 23 tickets it cost her

and we are told this equals $184; therefore we have

now we solve this equation the following way:





Thus, the regular price was $12.
To do this, multiply each of the four elements in matrix D by -1/2 or -0.5:
| 9 8 |
| -7 -4 |
These rates are not in proportion. Juan walked faster.
Explanation:
First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.
