Calculation:
It is given that,
Jamall is buying ingredients to make a large batch of granola.
He buys,
walnuts - 3.6 pounds for $4.53 per pound
cashews - 2.2 pounds for $6.35 per pound
He pays two $20 bills. So, he pays $40.
Then he gets back a change
= $40 - (3.6 × $4.53 + 2.2 × $6.35)
= $40 - ($16.308 + $13.97)
= $40 - $30.278
= $9.722 ≅ $9.72
Therefore, he gets a change of $9.22 back.
