a t-shirt that costs $14 without tax costs $14.98 with tax. what
is the sales tax percent?

7%

Step-by-step explanation:

14+Sale tax=14.98

14.98-14=sale tax

14.98-14=0.98

0.98 is the sale tax now we need to find the percent

Let represent t percent

14 of t%=0.98

14*t/100=0.98

we need to use inverse operation to isolate T on one side so if its multiplication we need to do division on both sides to un-due multiplication.

So to move 100 we need to multiply on both sides and we will get

14*t=0.98*100

0.98*100=98

14*t=98

to move 14 we need to divide

14/14=1

we dont need to put 1t becuase t is =1

so we just write it as t

98/14=7

t=7

so Sale tax percent is 7%

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

it is 570
