Three friends decide to share the cost to rent an apartment equally. The apartments that they are considering cost at least 1 200 per month. Write and solve an inequality to represent each person's share of the rental cost​
Lets highlight some key words.
There are three friends and they equally have to share an unknown amount of number to earn up to the 1200 per month,
X=Amount needed to pay the rent fee.
Since there are 3 friends and they have to split we have to multiply,
3x, "At least" is less than or equal to so .
3x
Additionally theres 1200 per month so the friends need to share there rent and 1200 is the total it should be put as
3x
$1200
To add up to the rent, and to solve the inequality
we have to do the opposite of multiplication, and divide.
1200/3 = 400, x
400
