I need help with this, it just doesn’t make sense to me.

2 hundred dollar bills is $200. 6 twenty dollar bills is $120. 5 ten dollar bills is $50. 18 one dollar bills is $18. 6 quarters is $1.50. 12 dimes is $1.20. a check for $200 is $200. a check for $11.12 is $11.12. add these up, you get $601.82
