PLEASE HELP ME Mal works at a photo gallery. He charges $50 for a large photo and $40 for a large frame. Sales tax is 5%. How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.

1. One way to calculate the total tax is 0.05(50 + 40). Use the order of operations to evaluate this expression. Show your work.

Write your answer in the space below.

2. Use the distributive property to expand 0.05(50 + 40).

Write your answer in the space below.

3. Find the total tax using the expanded expression. Did you get the same answer as you did by evaluating the original expression?

Write your answer in the space below.

4. Which expression, the original expression or the expanded expression, involves finding the total cost first, then calculating the tax on that total?

Write your answer in the space below.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

it should be a.

hope it
