Answer:
Paper Lanterns: 4
Bags of Balloons: 12
Garlands: 11
Banners: 4
Explanation:
Cost of lanterns is $6.50
Mrs. Murphy bought 4 lanterns
Multiply the cost of one lantern ($6.50) by the number of lanterns bought (4)
6.50 multiplied by 4 equals 26
Cost of banners is $5.25
Mrs. Murphy bought 4 banners
Multiply the cost of one banner ($5.25) by the number of banners bought (4)
5.25 multiplied by 4 equals 21
Mrs. Murphy bought 3 times as many balloons as she did lanterns
So, you multiply the number of lanterns bought (4) by 3
This gives you 12
You then multiply the cost of each balloon ($5.00) by the number of balloons bought (12)
5.00 multiplied by 12 equals 60
Mrs. Murphy bought 7 more garlands as she did lanterns
So, you add 7 to the number of lanterns bought (4)
7 plus 4 equals 11
To find the cost of the total garlands bought
You multiply the cost of each garland ($3.50) by the number of garlands bought (11)
3.50 multiplied by 11 equals 38.5
Now you can add up the costs of all the items
26+21+60+38.5=145.50
145.50 was the total amount she spent so you know it is the correct answer.
