The answer is d: 280/70 =4 buttons per shirt multiply 460*4=1840 buttons needed
It would be D. 1840 buttons.
460 divide 70= 6.5714
Multiply how many buttons to make 70 shirts. 280x6.5714=1839.1960.
Change 1839 to a 1840 since there isn’t any 1839 and 1840 is about close to 1839.
Final Result: 1840 buttons.
