Question

Sam needs to cut a piece of sheet metal into eight pieces it takes him five minutes to make each cut how many cuts will sam make

Answer 1

you have to multiply the eight pieces by 5 because it takes him five minutes to cut one piece of metal

Answer 2

time=number of cuts times time it takes to make each cut

to cut something into 2 pieces, you need 1 cut
to cut into 3 pieces you need 2 cuts
therefor, to cut something into n pieces, it takes n-1 cuts
so 8piece is 8-1=7 cuts

time=number of cust times time per cut
time=7 times 5 minutes
times=35 minutes
