Thanks for the help, question below :)

a:

b: 5

c: 8

Step-by-step explanation:

Explanation for a: Making the equations

Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations since the total cost will be 800$, and we have a total of 13 ads.

Explanation for b: Solving for h

We can now solve for one of the variables using elimination. Let’s multiply the expression by -75.

Great! Now let’s add the equations.

Adding these equations, we get

Divide both sides by -35, and we get .

Explanation for c: Solving for f

We can now substitute h inside the equation .

Hope this helped!
