Answer:

Soda cost $5

Hamburger cost $15

Step-by-step explanation:

Let the price of soda be A and that of hamburger be B

From the question,a soda and hamburger cost $20 at a restaurant.

That’s

A + B = $20

Also,the hamburger costs $10 more than the soda

That’s

B = A + $10

We now have two equations

Equation 1 : A + B = 20

Equation 2: B = A + 10

Now substitute A + 10 for B in equation 1.

We have

A + A + 10= 20

2A + 10 = 20

Subtract 10 from both sides

2A + 10 - 10 = 20 - 10

2A = 10

Divide both sides by 2

A = 10/2

A = 5

A soda cost $5

Now substitute 5 For A in equation 2 to get B

B = 10 + A

B = 10 + 5

B = 15

B = $15

A soda cost $5 while the hamburger cost $15

Sandy is upgrading her Internet service. Fast Internet charges $40 for installation and $52.45 per month.
Orlov [11]

Answer:

After 8 months of internet use both the connection will cost the same.

Step-by-step explanation:

Fast Internet charges $40 for installation and $52.45 per month.

So, the total cost after using x months of the internet in Fast Internet will be  

C = 40 + 52.45x

Quick Internet has free installation but charges $57.45 per month.

So, the total cost after using x months of the internet in Quick Internet will be

C = 57.45x

Now, if those two cost are same then

40 + 52.45x = 57.45x

⇒ 5x = 40

⇒ x = 8

Therefore, after 8 months of internet use both the connection will cost the same. (Answer)
