33.90/5= 6.78 or 26.88/4= 6.72. The 4 boxes of chicken fingers has the cheaper unit price
Answer:
Let x = the unknown cost of a single hot dog and y = the unknown cost of a single soft drink. We have two unknowns so we need two equations to find them.
Equation 1 - 10 hot dogs and 5 soft drinks cost $35; that is 10x + 5y = 35
Equation 2 - 7 hot dogs and 4 soft drinks cost $25.25; that is 7x + 4y = 25.25
First let's re-write equation 1 to solve for y:
10x + 5y = 35
5y = 35 - 10x (subtract 10x from both sides)
y = 7 - 2x (divide both sides by 5)
Next, let's substitute 7 - 2x for y in equation 2:
7x + 4y = 25.25
7x + 4(7-2x) = 25.25
7x + 28 - 8x = 25.25
-x + 28 = 25.25
x - 28 = -25.25
Solve for x, the cost of a single hot dog. Once you have that, use y = 7 - 2x to find the cost of a single soft drink.

Hi!
The price per cup is $0.55 or 55 cents.
Since there are 16 cups in 1 gallon, we would need to find out how many cups are in 3 gallons by multiplying 16 by 3.

Now we know that there are 48 cups in 3 gallons. Since we have found the number of cups in 3 gallons, we can now divide the price by 48 to find out the price per cup:

After dividing the price by the number of cups, we have now found out the price per cup, which is: $0.55 or in other words, 55 cents.
Hope this helps! Good luck!
The cost for a party here is the base fee,
plus charges for any additional guests.
So we know for a 15-person party, the price is going to be $100. That's a flat (constant) cost.
We know that for each additional person, we add $12. So for

more people, the cost is $

.
Since 100 is constant here, we make that our y-intercept. Even with no additional guests, the cost is still $100.
We add to write

. 12 is the constant rate of change (slope).
