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]

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
