Answer:
Cost =$3
Amount = 8 gallons and 17 gallons
Step-by-step explanation:
Given
24 + 51
Required
Simplify to show the cost and amount of gas bought by each individual
24 + 51
[Factorize]
3(8 + 17)
The above can't be factored any further.
Since the cost of gas for both individuals is the same, we can conclude the following.
Cost = $3
This is so because it applies to both numbers in brackets
Amount of Gas = 8 gallons and 17 gallons respectively by both individuals
6% 5.34
_____ = _____
100% x

6x=534
divide both sides by 6
x=89
Answer=89

2.6x=2 (3-8y)
6x=3-8y
x=3/6-8y/6
x=1/2-4y/3
