Answer:
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
<em>Pauli's pizzeria</em>
we have
y=15x -----> slope m=$15 per pizza sold
<em>Leo's pizzeria</em>
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
