Answer:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = 12
Step-by-step explanation:
Given that:
Laqueta has three times as many quarters as Pablo.
They both spend $0.50.
After that Laqueta will have 5 times as many quarters as Pablo.
To find:
Number of quarters with Laqueta and Pablo now?
Solution:
Let number of quarters with Laqueta = [tex]x[/tex]
Let number of quarters with Pablo = [tex]y[/tex]
As per given statement:
[tex]x=3y ..... (1)[/tex]
In $0.50, there are 2 quarters:
After spending $0.50, number of quarters left with both of them:
Number of quarters left with Laqueta = [tex]x[/tex] - 2 = [tex]3y-2[/tex]
Money left with Pablo = [tex]y[/tex] - 2
As per given statement:
[tex]3y-2 = 5(y-2)\\\Rightarrow 3y-2 = 5y-10\\\Rightarrow 2y = 8\\\Rightarrow y = 4[/tex]
Therefore, the answer is:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = [tex]3 \times 4[/tex] = 12
