If you and 4 friends go to buy a drone and you find that it will cost you each $30. How many friends would you need to have with you if you wanted to get that cost down to $20/person or less.
I've been stuck on this question for a while now, if you could help I'd appreciate it.
Please help as soon as you can, thanks :D
5 * 30 = 150
150 / 20 >= ?
= 7.5 I know, I've tried that process, but it just doesn't make sense, 7.5 people?
You're right. You'd need 8 people. Note that you want to get the cost down to $20 or less per person.
Ahhh ok, thx for the help sry for the late reply haha
To determine how many friends you would need to have with you to reduce the cost per person to $20 or less, we can set up an equation based on the information given. Let's define the variables:
C = Total cost of the drone
N = Number of friends
According to the given information, you and your 4 friends are purchasing the drone, and each of you will contribute $30. Hence, the total cost can be calculated as:
C = (N + 1) * $30
To find the minimum number of friends required to bring the cost down to $20 or less per person, we need to solve the equation:
(N + 1) * $20 ≤ C
(N + 1) * $20 ≤ (N + 1) * $30
Simplifying the equation further:
20N + 20 ≤ 30N + 30
Combining like terms:
10N ≥ 10
Dividing both sides by 10:
N ≥ 1
This means that you would need at least 1 friend with you to get the cost down to $20 or less per person.
