The price for 3 sandwiches amounts to $18. Since the cost, c, of a ham sandwich directly correlates with the quantity, n, and is told that c equals $54 for 9 sandwiches, the cost per sandwich is $6. Multiplying $6 by 3 gives a total of $18.
Y = 6
Here’s a step-by-step explanation:
On the initial day of ticket sales, the school sold 3 adult tickets and 8 student tickets for a total of $72.
On the following day, the school collected $152 from 7 adult tickets and 16 student tickets.
What is the price of a student ticket?
Day 1: 3x + 8y = 72
Day 2: 7x + 16y = 152
This leads to a system of equations.
By manipulating these equations, we find:
Ultimately, y = 6.
If you wish to continue from this point, substituting y into the equation will give the value for x.
3 distinct arrangements - 1 x 9 (or 9 x 1) and 3 x 3
Thus, the total number of arrangements = 2 x 2 = 4 = an even count
Initially, we identify pairs of different factors of 9.
The pairs of factors for 9 are:
(1, 9) and (3, 3)
For each of these pairs, Mr. Deets can create 2 arrangements.
This means the total arrangements Mr. Deets can construct = 2 x 2 = 4, confirming that the overall number is even.
