Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Vaishali wears a beautiful piece of clothing called a Saree,  a traditional Indian dress for women.  It is mostly tangerine-colored, with blue, brown, and gold-colored decorative stripes.  There are three times as many gold stripes as brown stripes, and five times as many blue stripes as gold stripes. If there are 4 brown stripes, how many blue stripes does Vaishali's Saree have?With 3 times as many gold stripes as brown stripes, this means there are 3 * 4 = <<3*4=12>>12 gold stripes.
With five times as many blue stripes as gold stripes, this means there are 5 * 12 = <<5*12=60>>60 blue stripes.
#### 60[END]

After Bella’s ballet performance, she received 2 dozen roses from her parents, and 2 roses from each of her 10 dancer friends.  How many roses did Bella receive?Bella receives 2 x 12 = <<2*12=24>>24 roses from her parents.
She receives 2 x 10 = <<2*10=20>>20 roses from her friends.
She receives a total of 24 + 20 = <<24+20=44>>44 roses.
