We describe this as cost per envelope which tells you the cost gets divided by the number of envelopes.
$2.49/50 = 0.0498 cents per envelope
$5.50/90 = 0.0611 cents per envelope.
So the 90 for $5.50 costs more per envelope than the 50 for $2.49
Well we would know if you told us the ingridients
M=-20/7. .........!!!!!!!!
