Richard buys, fixes, resells small devices, like the mir487, which consistently needs a transistor replaced. he can buy the transistor for $8.10 and a broken mir487 for $51.90. once fixed, he resells the new mir487 for $224.96. approximately how much profit will richard make if he resells 10 mir487 devices? a. $2,170.00 b. $1,730.00 c. $1,650.00 d. $2,200.00

Calculate the profit on one device, and then multiply the result by 10.

Cost of broken Mir487 + cost of transistor + profit = $224.96
               $51.90           +        $8.10           +  profit + $224.96

                $60                                              + profit = $224.96

Profit on the sale of one refurbished Mir487:   $164.96

Profit on the sale of 10 refurb'd units:               $1649.60

Which of the four given possible answers is closest to $1649.60?
