Give the scale factor of figure b to figure a.
can you also do a step by step so i understand.

The figures are similar.

the side that is 16 on A is similar to the side that measures 4 on figure B

24 is similar to 6

32 is similar to 8

24 is 4 times 6

24 / 6 = 4

32 is 4 times 8

32 / 4 = 4

and 16 is 4 times  4

16 /4 =4

Figure A is 4 times bigger than Figure B. That is your scale factor.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
