4*20%
4*.2=
.8
4-.8=
3.2
The sales price would be $3.20
1/2 and 4/8! Both are equivalent!
I'm going to assume you pasted the question and answers and the fractions for the slope didn't come up.
Solve for the slope using the given values.
Slope formula: y2-y1/x2-x1
= 8-5/5-0
= 3/5
Point slope form: y - y1 = m(x - x1)
Using the point (5, 8) and the slope (3/5), it should look like:
y - 8 = 3/5(x - 5)
Best of Luck!
The answer's 22.4. You have to divide 548.8 miles by 24.5 gallons.
