Charlotte places 15 tulips and 6 violets in a bouquet. If tulips cost x and violets cost y, mark all equations which represent the cost of 20 bouquets.

300x+120y

Step-by-step explanation:

Given that Charlotte places 15 tulips and 6 violets in a bouquet.

Thus cost of one bouquet will include cost of tulips and violets

Cost of tulip in one bouquet = 15*x = 15x

Cost of viiolet = 6*y =6y

Total cost for one bouquet =

1 Bouquet costs =

So 20bouquets would cost

=

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
