Casey has n nickels. Megan has 4 times as many nickels as Casey has. Write and expression for the total number of nickels Casey

AnnyKZ [126]

Step-by-step explanation:

Let n be the number of nickels that Casey has.

We are told that Megan has 4 times as many nickels as Casey has, therefore, the number of nickels that Megan has will be 4*n.

Now we will add the amounts of nickels that Casey and Megan have to find the total amount of nickels.

$\text{Total number of nickels Casey and Megan have}=n+4*n$

Therefore, the expression $n+4*n$ will represent the total number of nickels that Casey and Megan have .

Upon combining like terms we will get,

$\text{Total number of nickels Casey and Megan have}=(1+4)n$

$\text{Total number of nickels Casey and Megan have}=5n$

Therefore, Casey and Megan have 5n nickels.
