Answer:
A. The Long family paid $2.63 too little for their purchases.
Step-by-step explanation:
We have been given that the Long family spent $38.62 for school supplies and $215.78 for new school clothes. They paid 6.8% sales tax on their purchases.
First of all, we will add both amounts as:
Now, we will find 6.8% of 254.40.
Upon adding $254.40 and $17.2992, we will get total amount paid by Long family.
Now, we will subtract $271.6992 from $269.07:
Since the long family paid $2.63 less than actual amount, therefore, the Long family paid $2.63 too little for their purchases and option A is the correct choice.
