The diagram shows a rug laid on a wooden floor. it’s width is 2m less than the width of the room a) write an equation to represent the width of the room (y)
b) write an equation to represent the area of the rug, which is 3m^2
c) use these two equations to find the value of x and hence the width of the room (y)

70,000 + 6,000 + 800 + 30

step-by-step explanation:

in total they made   333.74 your welcome : d

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
