Question

Lola bought x pencils that cost $0.25 each and y erasers that cost $0.50. She spent less than $3. Which graph represents Lola’s purchase?

Answer 1

Answer:

Inequality is $0.25x+0.5y\leq 3$ and the graph is shown below.

Step-by-step explanation:

Let the number of pencils bought = x and the number of erasers bought = y.

Now, Cost of 1 pencil = $0.25. So, the cost of x pencils = 0.25x dollars

Also, Cost of 1 eraser = $0.5. So, the cost of y erasers = 0.5y dollars

Since, she spent less than $3.

So, we have the inequality,

Cost of x pencils + Cost of y erasers ≤ Maximum amount spent

i.e. $0.25x+0.5y< 3$

So, the graph representing the inequality is given below.

Answer 2

X would have to be less than 12, y would have to be less than 6. So a graph displaying x less than or equal to 12 and y less than or equal to 6.
