Question

Casey has n nickels. Megan has 4 times as many nickels as Casey has. Write an expression for the total munber of nickels Casey and Megan have. Then simplify the expression.

Answer 1

C = n
M = 4 x n or 4n
C + M = n + 4n = 5n

Answer 2

Total number of nickels Casey and Megan have:
`n+4n`

Simplified:
`5n`

Explanation:

• Casey has
  `n` nickels

Megan has 4 times of Casey. So we multiply 4 with the number of nickels Casey have,
`n`

• Megan has
  `4n` nickels

Total nickels of Casey and Megan = n + 4n

Simplified = n + 4n = 5n
