Sara and her sister Emily both collect charms for the their charm bracelets. Together they have 42 charms. Emily has 2 more charms than Sara. To figure out the number of charms each girl has, you must first identify the conditions. What are the conditions of the problem?

a) how many charms Emily has; how many charms Sara has
b) together they have 42 charms; Emily has 2 more than Sara
c) together they have 42 charms; how many charms Emily has
d) Emily has 2 more charms than Sara; how many charms Sara has

You can make an equation like this.

Give Sara a variable like x.
And let Emily be x+2.

x+(x+2)=42
2x+2= 42
-2 -2
2x= 40

2x/2 = 40/2
x=20 (Sara) x+2= 20+2= 22 (Emily)

The correct answer is d) Emily has 2 more charms than Sara; how many charms Sara has.

This condition provides all the necessary information to solve the problem. It states that Emily has 2 more charms than Sara and does not mention the specific number of charms each girl has or the total number of charms they have together. Therefore, the condition mentioned in option d) is the one that identifies the problem's conditions accurately.
