Mark brought 3 cds for 29.99 what is the least amount of 20 will he need

Question

Hello how u I need help with this question... show me how u come up with the answer please... Thanks

 

Answer 1

Andrea, are we talking $20 bills?  Then you need to find out how much $29.99 x 3 is (hint- make 29.99 into 30, multiply by 3 and then take away 3 cents from the answer), then figure out how many $20 bills he needs to make that much.

 

Does this help?
