Agroup of friends receives a dinner bill for $87.50. the sales tax rate is 5%. they want to leave a 15% tip on the total bill after tax. how much money will they pay for their dinner with tax and tip?

$13.78

Step-by-step explanation:

87.5x.05=4.38

87.5+4.38=91.88

91.88x.15=13.78

I got 105.66

Step-by-step explanation:

87.50(.05) = 4.375(or 4.38)

87.50 + 4.375 = 91.875

87.50(.15) = 13.125

91.875 + 13.125 = $105.66

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
