Emily wants to have her Photo album printed. The printing company charges $24.50
for the first book, and then a flat rate for each additional book. Emily pays $48.50 for 4
books. How much is the flat rate after the first book is purchased?

$8 flat rate

Step-by-step explanation: First subtract 24.50 from 48.50 to find the amount that was charged for the 3 additional books.

48.50 - 24.50 = 24

So the remaining 3 books costed a total of $24

Next, we need to divide 24 by 3 to determine how much each additional book costs.

24/3 = 8

So, the flat rate after the first book is purchased is $8 per additional book.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

a is the right answer
