Step-by-step explanation:
25 (caculators) × $32 ( calculator cost)=$800 [(how much they costed when the owner order them it costed him $800)]
22 ( calculator that he sold) × $40 ( calculator cost) = $880 [( how much he made when he old them)]
$880-$6 ( because he had to return three calculators that he could not sell and had to pay a $2 charge for every one he return 3 (calculator)= $6) =$874(how much he made after selling that calculators
$874 - $800= $74
( he bought the cacaulators for $800 and sold them for $874 so you have to subtract the $800 dollars that he had to buy the calculators for, he made $74 )
