6x+12y=21l
x=5y
6(5y)+12y=21l
x=5y
30y+12y=21l
x=5y
42y=21l
x=5y
1l=2y
x=5y
x=12,5 l
y=2,5 l
2 gallons * $2.58 per gallon = $5.16 expenses (total spent)
2 gallons * 16 cups = 32 total servings
32 cups * $0.75 per cup = $24 gross revenue (total income)
$24 - $5.16 = $19.84 net revenue (profit)
4- 20
I created an equation for this one:
4x+x=100
- 4x= four times the amount of the other number
- x= the number
- combine like terms
5x=100
x=20
5. One pretzel costs $3
Create an equation:
Mulitply 2s+p=7 by -2 so you can use elimination.
Combine equations
p=3
The answer is going to be(2,1)
