Danica is arranging flowers for a party. On each table, t, there will be a vase of 9 flowers and 3 bowls of flowers with f flowers inside. Danica needs an additional 12 flowers for a cake topper. This situation can be written as the following expression:
9t + (3f)t + 12
How many flowers should Danica purchase if she has 21 tables with 3 flowers in each bowl?
another way to do it is to group the group all the flowers on each table, as in
(9+3f)t + 12
Now just plug in the numbers
9*21 + (3*3)*21 + 12 = 390
(9+3*3)*21 + 12 = 390
To find out how many flowers Danica should purchase, we need to substitute the given values into the expression:
9t + (3f)t + 12
Given:
Number of tables (t) = 21
Number of flowers in each bowl (f) = 3
Substituting the values:
9(21) + (3(3))(21) + 12
Calculating:
189 + (9)(21) + 12
189 + 189 + 12
378 + 12
390
So, Danica should purchase 390 flowers.
To find out how many flowers Danica should purchase, we need to substitute the given values into the expression and solve for the total number of flowers.
Given:
- Number of tables, t = 21
- Number of flowers in each bowl, f = 3
The expression is:
9t + (3f)t + 12
Substituting the given values:
9(21) + (3(3))(21) + 12
Now, let's solve it step by step:
First, calculate 9 times 21:
9(21) = 189
Next, calculate 3 times 3:
3(3) = 9
Now, multiply the result by 21:
9(21) = 189
Finally, add all the results together:
189 + 9(21) + 12 = 189 + 189 + 12 = 390
Therefore, Danica should purchase 390 flowers in total.
