## Jimboslice one year ago Part A: Maria rented a coat at \$285 for 3 days. If she rents the same coat for 6 days, she has to pay a total rent of \$510. Write an equation in the standard form to represent the total rent (y) that Maria has to pay for renting the coat for x days. (4 points) Part B: Write the equation obtained in Part A using function notation.(2 points) Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)

1. Ganpat

y = a +bx a is fixed cost, while b is variable cost so equation 1 & 2 are as follows, 285 = a +3b 510 = a + 6b can u solve for a & b ??

2. Ganpat

hellloo !! anybody home ??

3. Ganpat

Find a & b, substitute back in basic equation i.e y = a +bx.. thats solution for part A ..

4. Jimboslice

Oh sorry i didnt realize anybody answered my question!!

5. Ganpat

soo.. now u do have solution for part 1.. rt ??

6. fbi2015

can someone help me with a literature question?

7. fbi2015
8. Jimboslice

rt ?

9. Ganpat

oops !! sorry... right !!

10. Jimboslice

285 = a +3b 510 = a + 6b is the top equation im suppose to solve for A and bottom B ?

11. Ganpat

try solving them simultaneously.. u will get values for a & b..

12. Jimboslice

a=3n B=95 right ?

13. math&ing001

|dw:1385573421916:dw| replace b with it's value and solve for a.

14. Jimboslice

510= a +75 solve this ?

15. math&ing001

510=a+6*75

16. Jimboslice

a=60

17. math&ing001

Yes!

18. Jimboslice

how would i write out part A ?

19. math&ing001

Like @Ganpat said earlier: y=a+bx.

20. Jimboslice

i dont know how to do that

21. math&ing001

Just replace a and b with their respective values.
