Maryanne went to lunch with a friend. The bill was $35.60 before tax. Sales tax rate is 7.25%, and she decided to leave a 15% tip. What was the final total of her lunch bill?

$43.91

Step-by-step explanation:

Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.

$35.60 + $2.58 (tax) = $38.18

$38.18+ $5.73 (tip at 15%) = $43.91 total

hope this helps you!

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
