Answer:

0.75

Step-by-step explanation:

Using the equation

y=mx

where y is the cost, m is constant and x is variable representing packages

8.85=15x

5.1=10x

Subtracting equation 2 from 1 then

5x=3.75

x=3.75/5=0.75

x=0.75

The constant of proportionality is 0.75

ANTONII [103]

Answer:

There were 261 Cheeseburgers and 87 Hamburgers sold on Tuesday

Step-by-step explanation:

Lets write some equations where H=Hamburgers and C=Cheeseburgers:

1) H+C=348

2) C=3H

1) Substitute 3H as C in the first equation:

3H+H=348

2) Combine alike terms:

4H=348

3) Divide both sides by 4:

H=87

4) Now, substitute 87 as H in the first equation:

87+C=348

5) Subtract 87 from both sides:

C=261
