750 ml bottle of medicine costs $ 1.80 A 1.4 litre of the same medicine costs $3.50 a) Work out the cost for each bottle , in cents per milliliter .
b) Which bottle is better value for money ?​

The 750-milliliter bottle costs $ 0.0024 per milliliter, while the 1.4-liter bottle costs $ 0.0025 per milliliter, making the 750-milliliter bottle a better value.

Step-by-step explanation:

Given that 750 ml bottle of medicine costs $ 1.80, while 1.4 liter of the same medicine costs $ 3.50, to work out the cost for each bottle in cents per milliliter, and determine which bottle is better value for money, the following calculations must be done:

1.80 / 750 = 0.0024

3.50 / 1,400 = 0.0025

Thus, the 750-milliliter bottle costs $ 0.0024 per milliliter, while the 1.4-liter bottle costs $ 0.0025 per milliliter, making the 750-milliliter bottle a better value.

step-by-step explanation:

not sure about this one man

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
