Dan is comparing the cost of having printed and prepared by two companies

Kay [80]

For 4 copies, the total cost for preparing and printing will be the same.

Step-by-step explanation:

Let,

p be the number of pages

Company A;

Charges of preparing = $6

Charges of per page print = $2.50

A(p)= 2.50p + 6 Eqn 1

Company B;

Charges of preparing = $4

Charges of per page print = $3

B(p)= 3p + 4 Eqn 2

For equaling the cost;

A(p) = B(p)

$2.50p+6=3p+4\\2.50p-3p=4-6\\-0.50p=-2$

Dividing both sides by -0.50

$\frac{-0.50p}{-0.50}=\frac{-2}{-0.50}\\p=4$

For 4 copies, the total cost for preparing and printing will be the same.

You need to buy 8 packages of meat for a cookout. A package of hot dogs costs $2.19 and a package of hamburgers costs $5.89. You

Daniel [21]

Answer:

1.89x + 5.19y = 31.62.

Step-by-step explanation:

Let the pagke of hot dags be x

Let the pakage of hamburgers be y

Now they total up tp 8 packages.

xEliminate the cost

x+y=8

y=8-x

Cost of hotdogs = $1.89

Cost of hamburgers = $5.19

1.89x+5.19y=31.62

1.89x+5.19(8-x)=31.62

1.89x+41.52-5.19=31.62

-3.3x=--9.9

x=3

y=8-3

y=5
