Answer: 17.5 gallons
Step-by-step explanation:
The formula to solve this question will be: g = d/m
where, g = number of gallons of gasoline used
d = distance travelled = 315 miles
m = miles per gallon = 18 miles/gallon
Therefore, the number of gallons of gasoline that Darnell will need to travel 315 miles will be:
g = d/m
g = 315/18
= 17.5 gallons
Make it into y = mx + b
2y = -3x + 6
Divide by 2
Y = -3/2x + 3
The slope is -3/2
To make it easier to divide, turn the fraction 201/5 into decimal form which would be 40.2.
After that you can divide 74.94/40.2 and it should give you $1.86 per gallon.
