1.) suppose that you also want to buy a cake for the party. you go to the supermarket to buy a cake, and
see that all of the cakes they offer are square. the cheapest sheet of cake costs $15.60 and it serves
80 people. you can buy any fractional part of the cake and pay that fraction of $15.60. you are
asked to buy 4 of a full pan. how much would it cost you if the store charges 7% tax on top of the
amount you paid for the cake?

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

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

it would open into a square depending on the type of envelope i’m not sure about the second part
