(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
Answer:
Roughly the same as what?
Step-by-step explanation:

Above is the correct method to solve this question.
Bror did wrong while solving the question because we can't directly divide any equation.
Hope this helps!
A.
5(5+x)=6(6+4)
Solving for x:
5(5+x)=6(10)
5(5+x)=60
5(5+x)/5=60/5
5+x=12
5+x-5=12-5
x=7
b.
4(4+x)=3(3+5)
Solving for x:
4(4+x)=3(8)
4(4+x)=24
4(4+x)/4=24/4
4+x=6
4+x-4=6-4
x=2
