Answer:
256 hats.
Step-by-step explanation:
You can see that every week, the number of hats knitted increases times 4;
1st week: 4 hats knitted.
1st week: 4 hats knitted in total.
2nd week: 4 times as many hats knitted the first week; (4 x 4 = 16).
2nd week: 16 hats knitted in total.
3rd week: 4 times as many hats knitted the second week; (16 x 4 = 64).
3rd week: 64 hats knitted in total.
4th week: 4 times as many hats knitted the third week; (64 x 4 = 256).
4th week: 256 hats knitted in total.
