Jack and melissa were on a date for Valentine's day. The restaurant bill came out to 52 00. Jack left 62.40 to cover the check and gratuity. What percent of gratuity did he leave for the waiter

Jack left 16.66% of  gratuity for the waiter.

Step-by-step explanation:

Given:

Restaurant bill amount =  52.00

Total bill jack paid =  62.40

To find:

percent of gratuity Jack left for the waiter = ?

Solution:

Lets first find the amount jack gave has gratuity to the waiter

The amount given for gratuity =   62.40 -  52.00

The amount given for gratuity =   10.40

Now the percentage is

=

=

=  16.66 %

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

the answer is 1/4
