Lets label hot dogs as 'h' and soft drinks as 'd'

6h + 4d = 13
3h + 4d = 8.50

We can solve by process of elimination.

Subtract the first equation from the second one.

We get:

3h = 4.5

Solve for h

<span>h = 1.5 </span>

<span>That means that the hot dog costs $1.50 which is answer choice </span>D.

<span>Hope that helps :)</span>

Well, since they both bought the same amount of soft drinks, you can just subtract 8.50 from 13 to find out the cost of 3. 13-8.50=4.50. Then divide 4.50 by three to get the cost to of one! 4.50/3=1.50. It is 1.50$ for one hotdog, so D. Hope this helped!

Tobin is solving the equation 3(x - 1.25) = 11.25. His work is shown below.
castortr0y [4]

Answer: In the last steps, instead of multiply each side by 3, he has to divide each side by 3.

Step-by-step explanation:

Hi, Tobin makes the mistake in the last steps.

3(x-1.25) = 11.25  

3x-3.75= 11.25  

3x-3.75+3.75= 11.25+3.75  

3x = 15

Until this step is the work ok.

Now, instead of multiply each side by 3, he has to divide each side by 3:

So:

3x /3 = 15/3

x = 5

Feel free to ask for more if needed or if you did not understand something.
