You call your teacher and find out that the second part of the note should have said “sell four hot dogs and two bags of chips for $10.” What does that do for your system of equations now? With this new information, how much should each item cost? Again, show all of your work.

Answers

Answer 1

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation:

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips

Answer 2

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips

Answers

Answer:

27. C

28. D

Step-by-step explanation:

The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.

Solving this equation gives:

[tex]\frac{75+88+62+100+x}{5} = 86\\325 + x = 86 \cdot 5\\x = 430 - 325 = 105[/tex]

So D is the right answer for 28.

27 is c And 28 is d.

Serena spent $8.20 buying cupcake ingredients. At the school bake sale she charged $0.75 per cupcake. If she made a profit of $14.30, how many cupcakes did she sell?


What is the equation?
14.30 - 8.20 = 0.75c
8.20 + 0.75c = 14.30
0.75c - 8.20 = 14.30
14.30 - 0.75c = 8.20
