<u>Answer:</u>

B

<u>Explanation:</u>

<u>Solve for n:</u>

Subtract 8 on both sides.

5n + 8 = 30

       -8    -8

Divide by 5 on both sides.

5n = 22

---     ----

5        5

Getting a solution of 4 2/5.

n = 4 2/5

<u>Check:</u>

5(4 2/5) + 8 = 30

22 + 8 = 30

30 = 30

Nathan ordered one cheeseburger and one bag of chips for 3.75 jack ordered two cheeseburgers and three bags of chips for 8.25 kn
Elan Coil [88]

Answer:

cheeseburger is $3 and chips is $0.75

Step-by-step explanation:

Let price of cheeseburger be x while price of a bag of chips be y hence for the case of Nathan, we can write the equation as x+y=3.75. Similarly, for Jack, we can write it as 2x+3y=8.25

x+y=3.75 hence x=3.75-y and substituting this into the second equation we have

2x+3y=8.25

2(3.75-y)+3y=8.25

7.5-2y+3y=8.25

y=8.25-7.5=0.75

x=3.75-y=3.75-0.75=3

Therefore, price of cheeseburger is $3 and chips is $0.75
