Answer:
1.50
Step-by-step explanation:
X = hot dog price
Y = hamburger price
5X + 4Y = 16.50
4X + 5Y = 17.25
4(5X + 4Y = 16.50)
20X + 16Y = 66
5(4X + 5y = 17.25)
20X + 25Y = 86.25
Now subtract the equations:
20X + 16Y = 66
20X + 25Y = 86.25
9Y = 20.25
Y = 2.25
Hamburger is $2.25
4X + 5(2.25) = 17.25
4X + 11.25 = 17.25
4X = 6.00
X = 1.50
Hamburgers are $2.25
Hotdogs are $1.50
There are an infinite number of them.
Here are a few:
4/10
6/15
8/20
10/25
12/30
14/35
16/40
18/45
20/50
Also 318/795 .
0.5 gallons every day
1 weeks = 7 days
0.5 gallons x 7 days = 3.5 gallons every week
1 gallon = 16 cups
3 1/2 gallons = 3 1/2 x 16 = 56 cups
