While learning about money, children in a kindergarten class collected coins to practice using in their classroom store. The children collected two dollars and fifty cents in dimes. How many dimes did the children collect?

OpenStudy (anonymous):

first, how many dimes are in a dollar?

OpenStudy (anonymous):

10

OpenStudy (anonymous):

right, so since we have 2 dollars, this means we have how many dimes? (we'll get to the fifty cents next)

OpenStudy (anonymous):

20

OpenStudy (anonymous):
