Assuming that the order of selection is not important, this is a question of number of ways. In other words, the combination should be computed. That is,
Number of ways of selection 5 flowers = 12C5 = 12!/{5!*(12-5)!} = 12!/{5!*7!} = 792
Therefore, there are 792 ways in which 5 flowers can be selected from the available 12 flowers.
Answer:
$8
Step-by-step explanation:
After the shoe purchase, her balance was $50 -45 = $5.
After depositing her babysitting earnings, her balance was $5+25 = $30.
After buying pizza, her balance was $30 -42 = -$12.
<em>Assuming no overdraft charge</em>, her balance after depositing her earnings was ...
-$12 +20 = $8
Sally's balance on Sunday was $8.
Let's assume
the number of bags of candy =x
the number of bags of cookies =y
There were 5 more bags of cookies sold than candy
so, we get
Bags of candy cost $5.50
so, total cost of candy is
bags of cookies cost $3.50
so, total cost of cookies is
so,
total cost = (total cost of candy)+(total cost of cookies)
we get
total cost =5.50x+3.50y
so, we can plug
now, we can plug y
now, we can find y
so,
the number of bags of candy =4
the number of bags of cookies =9............Answer
