#13 is 3000 because since each T-shirt is $650 and they buy 4 you multiply and get $2600 and since she received 400 dollar change then you add that value to the total cost and get 3000 that means she paid 3000
#14 is a millennium
1 year is 365 days
1 decade is 10 years
1 century is 100 years
1 millennium is 1000 years
So it has to be 1 millennium since 1000 years is the most out of the others

1 part of 3 sections of a wall takes 1/4 of an hour, (.25 or 25% of an hour), (15 minutes is 1/4 of 60 minutes), so if it takes 15 minutes for one section to be painted & you have 3 sections,
(15+15+15) or (15×3)
= your answer
30 is the unlike term cause it doesn’t have a variable match like the others i don’t know if I did it wrong I’m sorry
