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? 69 189 378 390

just plug f = 3 and t = 21

and multiply ?

4. rishavraj

like the equation for total no of flowers is $9t + (3f)t + 12$ so after plugging t = 21 and f = 3 we get $(9\times 21) + (3\times 3\times 21) + 12$
