Answer:
c. 12x − 24 = 60
Step-by-step explanation:
x is the number of boxes Krys bought.
12x is the number of pastries in those boxes. 2·12 = 24 is the number of pastries in the boxes Krys kept for herself. Then the number of pastries Krys brought to the party is ....
... 12x -24
We are told that number is 60, so we can use this equation to find x:
... 12x -24 = 60
Answer:
Option C : 12x − 24 =60
Step-by-step explanation:
Given :
Krys bought x boxes of pastries to bring to a party.
Each box contains 12 pastries.
She decides to keep two boxes for herself.
She brings 60 pastries to the party.
To Find : Equation can be used to find the number of boxes, x, Krys bought.
Solution :
Krys bought x boxes of pastries .
Each box contains 12 pastries.
So, total pastries she bought = 12 x
She decides to keep two boxes for herself.
Since 1 box contain 12 pastries .
Thus two box contains pastries = 12*2 =24 pastries
Now total pastries she bought is 12 x . Out of which she decides to keep 24 pastries . after keeping 24 pastries from 12 x pastries she bought 60 pastries to the party i.e.
⇒ 12 x - 24 = 60
Thus,Equation can be used to find the number of boxes, x, Krys bought:
12 x - 24 = 60
Hence Option C is correct .
