Answer:
#3 - y=4
#4 - x=-1
Step-by-step explanation:
With #3 you are only puting the y-value.
With #4 you are only putting the x-value.
If you were asking for how many packages you would like if each you would want one pack of crackers, and two packages of cheese. Simple math. The reason why you get that answer and that equation/solution, is by simply make ing the cheese grater then the crackers, but if the cheese is lower then the crackers, you get more cheese packages because then you get two times the cheese and you will have enough cheese for all the crackers. You may have a little bit of cheese left, but who doesn't like it plain? That is the answer.
a.
h = 2c - 3
b.
3h + 1.5c = 201
c.
We have a system of equations from part a and b.
h = 2c - 3 (equation 1)
3h + 1.5c = 201 (equation 2)
We use substitution method to solve this system.
Substitute equation 1 in equation 2 to get
3h + 1.5c = 201
>> 3(2c - 3) + 1.5c = 201
>> 6c - 9 + 1.5c = 201
>> 7.5c = 201 + 9
>> 7.5c = 210
>> c = 210 / 7.5
>> c = 28
Plug this value back in equation 1 to get
h = 2c - 3
>> h = 2(28) - 3 = 56 - 3 = 53
So, c = 28 and h = 53 implies that <u>28 corndogs</u> and 53 hotdogs were sold.
