Need one asap, Mark owes his sister $15. He earned $20 for mowing the grass. He have 1/5 of his earnings to a local charity and then paid his sister. Does mark have enough to repay his sister the full amount? Why?
because one fifth of 20 is 4, so if he donated 4 dollars to charity he will have 16 dollars left. After giving his sister the money he will have one dollar left. Hope I read that right : )
