For every 2 dollars that pam saves in her account, her brother saves 5 in his account.
if pam has 40 dollars in her account, how much money does her brother have in his account?

When pam saves 2, brother saves 5

so if Pam has 40

40/2 (the number of dollars Pam saves) = 20 

20 x 5 = 100 ( the number of dollars her bro saves)

her bro has 100 dollars

hope this helps

basically divide 2 from 40 and then multiply the answer with 5, and you get the number of money her bro saves

hope this helps

The density of the cube is 40
