Answer:
300 chapter books
Step-by-step explanation:
Given that:
Total books = 500
Ratio given = 2:3
So they are divided into 5 parts
Each part contains = 500/5 books = 100 books
So The chapter books have 3 parts
Chapters books = 3 * 100 = 300 books
i hope it will help you!
Let k be the constant of proportionality. Then we use it as follows:
2k + 3k = 500, or 5k = 500, or k = 100.
Thus, the number of picture books is 2(100) = 200, and the number of chapter books is 3(100) = 300.
As checks: 200 + 300 = 500 (books), and
200
-------- = 2/3, as specified in the problem.
300
Sales tax = $2.79
(18 x 48.6) /100
= 8.748 = $8.75 tip amount total
48.60-8.748 = 39.852 sales total
(39.852 x 7)/100
= 2.78964 = $2.79 sales tax
39.852 - 2.78964 = 37.06236 = $37.06 cost of bill
Sales tax was asked = $2.79
c) 2x⁵ + 11x³ - 5x²
f(x) - g(x) = 2x⁵ + 7x³ - (-4x³ + 5x²)
= 2x⁵ + 7x³ + 4x³ - 5x²
= 2x⁵ + 11x³ - 5x²
