Charlotte bought 46 pens and pencils.
Each pen costs $6 and each pencil costs $4.
How many penicls she buy?
anser is 1
42 + 4
7(6) + 4(1)
To find out how many pencils Charlotte bought, we can use the information given.
Let's assume that the number of pencils Charlotte bought is "x".
We also know that Charlotte bought a total of 46 pens and pencils. Therefore, the equation we can form is:
x + (46 - x) = 46
Simplifying this equation, we have:
x + 46 - x = 46
By canceling out the x terms, we are left with:
46 = 46
This equation is always true, indicating that any value of x would satisfy the equation. Therefore, we can conclude that Charlotte bought any number of pencils.
