Question

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)

Answer 1

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 ??

Answer 2

hellloo !! anybody home ??

Answer 3

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

Answer 4

Oh sorry i didnt realize anybody answered my question!!

Answer 5

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

Answer 6

Answer 8

rt ?

Answer 9

oops !! sorry...

right !!

Answer 10

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

Answer 11

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

Answer 12

a=3n B=95 right ?

Answer 13

replace b with it's value and solve for a.
