Question

A class is selling granola bars for a fundraiser. They earn $.075 for every granola bar sold. They have ordered 300 granola bars for the sale. The function P(b) = .75b represents the profit (P) the class earns for each bar (b) they sell. Find a reasonable domain and range for this scenario.

Answer 1

As the object is granola bars hence it may start from 0 and it ends at 300

Hence

Domain:-

$\\ \sf{:}\dashrightarrow 0\leqslant x\leqslant 300$

And

$\\ \sf{:}\dashrightarrow 0.75(300)=225$

Hence

Range:-

$\\ \sf{:}\dashrightarrow 0\leqslant y\leqslant 225$

Answer 2

Domain~

0⩽b⩽300

Range~

0⩽p⩽225

Hope this helps :)
