FIRST PART OF QUESTION:
Divide the total paid by the total cost of 3 packets (bundles)
$21.75 ÷ $1.45 = 15 (bundles)
then multiple that total [which is 15(bundles)] by the total of rice cracker packets per $1.45 [which is 3]
(15 x 3 = 45) - answer to first part of question
SECOND PART OF QUESTION:
remember, a packet (bundle) of 3 cost $1.45
first, divide the number of individual packets (60) by the number of "bundle" per $1.45 (3)
60 ÷ 3 = 20 (bundles)
to find the dollar amount of the 20 bundles; multiple by the price per bundle ($1.45)
20 x $1.45 = $29
YES is the answer
