The number of cars (c) in a parking lot increases when the parking lot fee (f) decreases. Right there correct equation for the scenario, and for the number of cars when the fee is six dollars.

If fee be y and cars be x

This is an inverse proportionality

• k is a constant of proportionality

• when c is 15, f is 20, therefore;

• Therefore, the equation is :

→ when f is 10:

negative shows decrease

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
