Answer:
$55
Explanation:
cost of one book = $25
cost of 2 books = 2*$25
=$50
tax charged = 10 %
tax amount = tax percent /100 *total cost
=10/100 * $50
=$500/100
=$5
total amount to be paid = cost of 2 books + tax amount
=$50 + $5
=$ 55
55
because 25x2 is 50 then multiply that by .10 and you get 5 then you add the 5 to the 50 and you get 55
