The equation y=15x can be used to determine the amount of money y pauli's pizzeria makes by selling x pizzas . the graph shows the money leo's pizzeria takes in for different numbers of pizzas sold. which pizzeria makes more money per pizza

Pauli's pizzeria make more money per pizza

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find out the slope of the graph of Leo's pizzeria

looking at the graph take the point (2,24)

The graph show a proportional relationship (the line passes through the origin)

The slope is m=y/x

we have

For x=2, y=24

substitute

m=24/2=$12 per pizza sold

The linear equation is

y=12x

step 2

Compare the slopes

Pauli's pizzeria

we have

y=15x -----> slope m=$15 per pizza sold

Leo's pizzeria

we have

y=12x -----> slope m=$12 per pizza sold

$15 per pizza sold > $12 per pizza sold

therefore

Pauli's pizzeria make more money per pizza

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
