Answer :
Final answer:
Kensington Hardware increases its hammer order by 5 each month. After ordering 36 in August, they will order 41 hammers in September.
Explanation:
If Kensington Hardware ordered 21 hammers in May and continued to order 5 more each following month (26 in June, 31 in July, 36 in August), then we can determine that this is a sequence with a common difference of 5. So, the number of hammers the store will order in September is the number ordered in August plus 5.
Number of hammers ordered in September = Number of hammers ordered in August + 5
Number of hammers ordered in September = 36 + 5 = 41 hammers.
