Question

Mrs. Glaus is decorating

the house for the holidays.
She spent $39 on 1 wreath
and 10 ornaments. The next
day, she went back to the
store and spent $63 on 6
wreaths and 3 ornaments.
What is the cost of a
wreath and the cost of an
ornament?​

Answer 1

A wreath costs $9 and an ornament costs $3

Explanation:

Let x = cost of a wreath and y = cost of an ornament. Your equations would be: x+10y=39 and 6x+3y=63. From there, you do simple subtraction to find that x=39-10y. You put that in to your second equation and get 234-60y+3y=63, or 234-57y=63. You simplify to get 57y=171. Do some division and get that y=3. If you plug that into your first equation, you get x+30=39, meaning that x=9. Have a great day!
