Option B is correct choice.

Step-by-step explanation:

1 backpack for $16.89

5 spiral notebooks for $1.19 each so total cost =

1 pack of mechanical pencils for $3.68

2 packs of lead refills for $1.88 each so total becomes =

Total becomes : 16.89+5.95+3.68+3.76=$30.28

Sales tax on the purchase = 5 % the value is 0.05*30.28=1.514

Now total cost becomes = 30.28+1.514 = $31.794

Leonardo has 2 coupons, each for 45 cents off on the purchase of a pack of lead refills. That means he got 90 cents off on both packs. So, new total Leo has to pay is : 31.794-0.90 = $30.894

Hence, Leo paid $30.89 in total. So, he paid the correct amount.
