Unit rate refers to how much the buyer paid per unit. Let’s do the math:
$2.52 for 4.5 pounds of potatoes Divide $2.52 by 4.5 The shopper paid 56 cents per pound of potatoes. Now $7.75 spent for 2.5 pounds of broccoli. Divide $7.75 by 2.5. The shopper paid $3.10 for each pound of broccoli. Last $2.45 for 2.5 pounds of pears. The shopper will spend 98 cents per pounds of pears. Please vote my answer brainliest! Thanks.
