First, you would find out how much 1 gallon of gas would cost
You would calculate $19.46 divided by 14 gallons
Your quotient is $1.39
Then, you would divide how much money you actually have ( $8.70 ) by how much 1 gallon is ( $1.39 )
You get 6.25...
But since you cannot by 1/4 a gallon, you would round your quotient down to 6
Solution : 6 gallons
Mark brainliest if this helped :D
We have 20% and 60% solutions and need 80 ml of 50%
A) x + y = 80
B) .20x + .60y = (80 * .5)
Multiplying A) by -.2
A) -.2x -.2y = -16 Then adding this to B) we get
.4y = 24
y = 60 ml of 60%
x = 20 ml fo 20%
