Answer:
$1.10
Step-by-step explanation:
We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.
First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.
Now, we will divide $5.50 by 5 to find cost of each avocado.
Therefore, the cost of each avocado is $1.10.
Let a = Adult tickets, s = Student tickets; we are going to set up a system of equations.
8a + 4s = 880
a - s = 20
We are going to multiply the second equation by so that we can cancel out one of the variables and solve for the other. This gives you:
8a + 4s = 880
4a - 4s = 20
Notice the s-variables will cancel:
12a = 900
a = 75
Now we plug in the amount of adult tickets to solve for the student ones.
75 - s = 20
- s = - 55
Divide both sides by - 1
s = 55.
There were 55 student tickets sold and 75 adult tickets.
Answer:
42 AND 46
Step-by-step explanation:
Answer:
$1083
Step-by-step explanation:
Let the actual amount be x
So since 12% convenience fee is given
It means 12%of x
That's 12/100×x
And he paid $130
So let's solve
12/100 ×x=130
12x/100=130
12x=100×130
12x=13000
Let's make x the subject of formula by dividing both sides by 12
x=1083.333
Approximately 1083
Therefore the actual fee is $1083
