Question

A video store charges the same fee each day a video is returned late. Craig returned a video 4 days late and paid a $3 fee. 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.

Answer 1

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**

$\frac{3dollars}{4 days}$=$\frac{X}{7 days}$

Now cross multiply

21=4x

x=5.25

Same results

Answer 2

$5.25 if returned 7 days late
