Answer:
The rule could cost 24 cents at most.
Step-by-step explanation:
Let x cents be the price of the ruler.
Alice is 22 cents short, so Alice has x - 22 cents.
Betty is 3 cents short, so Betty has x - 3 cents.
When they combine their money they have
x - 22 + x - 3 = 2x - 25 cents.
This amount is still not enough, so
Solve this inequality:
The rule could cost 24 cents at most.

Answer:
The answer is below
Step-by-step explanation:
The table shows the ratio between the number of books ordered and their cost: Number of Books Cost (dollars) 7 21 8 24 9 27 Find equivalent ratios when the number of books ordered is 1, 2, and 3. Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid.
Answer: Let the number of books be represented as x and the cost (dollars) be represented as y. From the table the ordered pairs in the form (x, y) can be gotten. (7, 21), (8, 24), (9, 27). To get the relationship between the number of books and the cost, we can use the formula of a straight line.
Using point (7, 21) and (8, 24):
When the number of books ordered is 1, 2, 3 the following pairs are:
For x = 1. y = 3x = 3(1) = 3
For x = 2 y=3x = 3(2) = 6
For x = 3 y = 3x = 3(3) = 9
The ordered pairs are (1, 3), (2, 6), (3, 9)
The graph is attached
To plot the ordered pairs, the number of books are plotted on the x coordinate and the cost on the y coordinate
