Step-by-step explanation:
Substitute n = 1 into each of the expressions
8n + 6
= 8(1) + 6
= 8 + 6
= 14
2(4n + 3)
= 2(4(1) + 3)
= 2(4 + 3)
= 2(7)
= 14
14n

Answer:
Number of Chicken Burritos purchased=7
Number of Cheesy Gordita Crunch purchased=6
Step-by-step explanation:
Let x be the number of Chicken Burritos and y be the number of Cheesy Gordita Crunch.
Total number items purchased=13
Total cost of 13 items=$28.17
Cost of each Chicken Burritos=$1.89
Cost of each Cheesy Gordita Crunch=$2.49
We have to find number of each items purchased.
According to question
.....(1)
...(2)
Equation (1) multiply by 2.49 and then subtract equation (2) from (1)
![0.6x=4.2](https://tex.z-dn.net/?f=0.6x%3D4.2)
![x=\frac{4.2}{0.6}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B4.2%7D%7B0.6%7D)
x=7
Substitute x=7 in equation (1)
![7+y=13](https://tex.z-dn.net/?f=7%2By%3D13)
![y=13-7=6](https://tex.z-dn.net/?f=y%3D13-7%3D6)
Number of Chicken Burritos purchased=7
Number of Cheesy Gordita Crunch purchased=6
