Question

Compare the rates to find which is greater.

50 envelopes for $2.49 or
90 envelopes for $5.50

Answer 1

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
