Find the unit price of both numbers then compare which one is a better deal

The 20oz one is the better price.

Step-by-step explanation:

The first one is 9 cents per bottle and the other on is about 10 cents per bottle.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2
