Write a proportional equation that can be used to find the late fee for a video that is returned 7 days late. What is the fee for a video that is returned 7 days late? Explain how you know.

Respuesta :

Answer:

$5.25 if returned 7 days late

Step-by-step explanation:

So we know that 4 days late is 3 dollars

We can find the unit rate

3/4 is 0.75

So 75 cents for every late day

Now we just multiply that by 7

0.75*7=5.25

so 7 days, 5.25

**porportional relationship equation**

[tex]\frac{3dollars}{4 days}[/tex]=[tex]\frac{X}{7 days}[/tex]

Now cross multiply

21=4x

x=5.25

Same results

$5.25 if returned 7 days late
