Question

Sharon went to a craft store with $9.00. She bought a doll for $2.25 and 5 key chains with the

remaining money. There was no tax, and all the key chains were the same price. After buying the
doll and the 5 key chains, she had no money left. WRITE AN EXPRESSION TO DETERMINE THE COST THE KEYCHAINS

Answer 1

The equation is...
$2.25 + 5x = 9.00


How to solve it!
Subtract $2.25 from both sides.
This leaves you with 5x = $6.75
Now divide 5 on both sides.
Now you end up with x = $1.35

Each keychain is $1.35

Answer 2

2.25 + 5x = 9.00

Hope this helps :)
