Will give brainlest 20 pointsthe total cost for sophia to build b birdhouses is represented by the function f(b)=3.5b+24. what does the value 3.5 represent in this situation? for each birdhouse built, the total cost decreases by $3.50. for each birdhouse built, the total cost increases by $3.50. the initial cost is $3.50. the total cost to build b birdhouses is $3.50.

For each birdhouse built, the total cost increases by $3.50.

Let's try some of the answers and see if they work.

The "initial cost" will be the cost when 0 birdhouses are built.

... f(0) = 3.5·0 +24 = 24 . . . . . clearly, not $3.50

Then increasing the number of birdhouses by 1, the cost is ...

... f(1) = 3.5·1 +24 = 27.5 . . . . . the cost has gone up (not down) by $3.50

Clearly the total cost to build 1 birdhouse is not $3.50. (It is $27.50.)

___

Our exploration of the formula leads us to conclude ...

... For each birdhouse built, the total cost increases by $3.50.

good luck!
