Yolanda purchased a meal at her favorite restaurant for $5.50. She tipped her waiter 20% of the purchase. Including the tip, what was the total amount of money that she spent at the restaurant? *

Yolanda spent $6.60 at her favourite restaurant, including the tip.

Step-by-step explanation:

We know that 20% of 5.50 is: 1.10

So, 5.50 + 1.10 = 6.60.

Yolanda spent $6.60 at her favourite restaurant, including the tip.

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
