a. $14.45 b. $5.55 c. $12.55 d. $7.45

Answer 1

STEP 1:
multiply number of pounds purchased by price per pound

= 3.4 pounds * $4.25 per pound
= $14.45 total cost


STEP 2:
subtract total cost of purchase (step 1) from amount she gave cashier ($20.00)

= $20.00 - $14.45
= $5.55 amount received back from cashier


ANSWER: (B) $5.55 received back

Hope this helps! :)
