Jack collected 360 ship models. 40% of them were made by him. If Jack donated 25% of models which he made and donated 50% of models he bought, how many fewer models made by himself were donated than those he bought? fewer models donated made than bought​

Answer 1

How many fewer models made by himself were donated than those he bought is 72

First step is to calculate the models that was made by Jack

Jack Models =360 × 40%

Jack Models= 144

Second step is to calculate the models that was bought by Jack

Models  bought= 360 – 144

Models  bought= 216

Third step is to calculate the amount of models made donated by  of Jack

Models donated=144 × 25%

Models donated = 36

Fourth step is to calculate the amount of models bought by Jack  donated

Models donated=216 × 50%

Models donated= 108

Now let determine the how many fewer models made by himself were donated than those he bought

Fewer models made=108 – 36

Fewer models made= 72

Inconclusion How many fewer models made by himself were donated than those he bought is 72
