Question

Please help ASAP. I don't understand this ​

Answer 1

you have 2450 bills each of which has the value of one dollar and they altogether weigh 5 pounds. so each dollar weighs

`(5)/(2450) \: \: pounds`

now if get a stack of 1470 bills, they should weigh

`1470 * (5)/(2450) = 3 \: \: \: pounds`
