D its really basic math you can also just do it in a calculator lel
Josiah would need 10 gallons to travel 265 miles.
First we divide 79.5 by 3 to find out how many gallons are needed for one mile.
79.5/3=26.5
For one mile we need 26.5 gallons of gas.
Now we will divide 265 by 26.5 to find the answer to the problem.
265/26.5=10
Josiah will need 10 gallons of gas to travel 265 miles

Answer:
Credit remaining after 21 minutes = $30.4
Step-by-step explanation:
Credit remaining on a phone card is a linear function of the total calling time.
When graphed, let the linear function representing the line is,
y = mx + b
Where 'm' = slope of the line
b = y-intercept
From the graph,
Slope of the line = -0.12
y = -0.12x + b
If this line passes through a point (33, 28.96),
28.96 = -0.12(33) + b
b = 28.96 + 3.96
b = 32.92
Therefore, the linear function is,
f(x) = -0.12x + 32.92
where x = calling time
Credit left in the card after 21 minutes,
f(21) = -0.12(21) + 32.92
= -2.52 + 32.92
= $30.4
