Y = 5/4x + 2
y - (-3) = 5/4 ( x - (-4))
1. Distribute 5/4
y + 3 = 5/4x + 5
2. Subtract three to collect like terms
y = 5/4x + 2

this is the correct way to solve these types of exercises
then we will try to do the same where a is (6+9x) and b is 24

and solve the right inequality for x

subtract 6 for all expression

now divide on 9

ok, this means that the x values will be from -10/3 to 2 including these

solution is the red zone
First divide the price of the olive oil by the volume of the olive oil to find the price per ounce. 5.88/25oz=0.2352 dollars/ounce. Then you have to multiply the volume of the bottle by .60 to find what 60% of the volume is. 0.60x25=15 ounces. since in the first two weeks she used 15 ounces which has a price of 0.2352 dollars/ounce you have to multiply 15 by 0.2352 which equals 3.528 dollars.
