Answer 1

One pound of pretzels is 5.75. You want to find the cost of
`2 (1)/(4)` of preztels. What you do is 5.75 ·
`2 (1)/(4)`, which results into:
12.9375 dollars of preztels

One pound of sugar is 3.25. You want to find the cost of
`2 (1)/(4)` of sugar . What you do is 3.25 ·
`2 (1)/(4)`, which results into:
7.3125 dollars of sugars

You subtract
12.9375 by 7.3125 and you get:

$5.625 difference

Answer 2

2 1/4=2.25
2.25*5.75-2.25*3.25=2.25(5.75-2.25)=2.25*3.50=7.875 ≈ 7.88
