Answer:
The better deal would be to buy the 50 envelopes for a total of $2.49
Step-by-step explanation:
Identify what you know:
1) You can buy a pack of 50 envelopes for $2.49
2) You can buy 90 envelopes for $5.50
Divide the number of enveloped by the prices, to find the price of ONE envelope in the pack. See:
$2.49/50 envelopes = $0.0498
$5.50/90 envelopes = $0.061
Also... where is THIS person buying envelopes... I want that price....
The second equation would be correct if x = 4.
6x / 8 = 3 6 x 4 = 24 and 24 / 8 = 3
You would take 9x3 and get 27 and then add that to 21 which is 48 and then divide 48 by 3 and get 16 so 16in each case
