Mrs. Gomez is a mother to 2 boys. The number of children she has is three times the number of boys she has. Her children are planning to buy her a bouquet of flowers. What is the biggest bouquet they can buy in which the ratio of pink flowers to blue flowers matches the ratio of girls to boys if the florist has 9 blue carnations and 12 pink carnations left?

Respuesta :

2*3=6 children Mrs Gomez has

6-2= 4 girls she has

pink carnations/ blue carnations= 4/2=2
⇒ numbers of pink carnations= 2* blue carnations

12 pink  carnations and 6 blue carnations

We want to see what is the biggest bouquet that Mrs. Gomez's children can buy for the given restrictions.

The biggest bouquet they can buy has 18 flowers.

We know that she is a mother of 2 boys, the total number of children is 3 times the number of boys, then she has:

2*3 = 6 children in total.

2 are boys, 4 are girls.

The ratio between girls and boys is:

4/2 = 2

Meaning that there are 2 times as many girls as boys.

Then they must buy the double of pink carnations as the number of blue carnations.

There are 12 pink carnations left and 9 blue carnations left, so the maximum number of pink carnations they can buy is 12.

And they must buy half of that of blue carnations, so they just need to buy 6 blue carnations.

So the total number of flowers in the bouquet is 12 + 6 = 18

The biggest bouquet they can buy has 18 flowers.
