Answer: the number of tiles will be 49
Step-by-step explanation:
Let x represent the number of tiles that Joshua can buy at either stores.
one store for $0.99 per tile but he he will have to rent a tile saw for $25. Let the total cost of buying x tiles in this store be y. Therefore
y = 0.99x + 25
At another store, he can buy a tile for $1.50 per tile and borrow a tile saw for free. Let the total cost of buying x tiles in this store be z. Therefore
z = 1.5x
To determine the number of tiles for which both costs will be the same, we will equate y to z. It becomes
0.99x + 25 = 1.5x
1.5x - 0.99x = 25
0.51x = 25
x = 25/0.51
x = 49
Answer: The bookstore receive 9 boxes.
Step-by-step explanation:
Hi, to answer this question we have to divide the number of books (200) by the number of books that each box contains (24 if it is full).
Mathematically speaking:
200 /24= 8.3333333
This means that the bookstore receives 8 full boxes and 1 box that isn't full.
8 x 24 = 192 books
200 -192 = 8 books (the 9th box will contain 8 books)
In conclusion, the bookstore receives 9 boxes.
