Quan is shopping. He can but two pairs of pants and one shirt for $79.85 (before tax is added). He can buy one pair of pants and two shirts for $69.85 (before tax is added). how much does a shirt cost?
To solve this question, let's use the information given.
We know that Sara and her sister Emily together have 42 charms. We also know that Emily has 2 more charms than Sara.
Let's assume that Sara has x charms. Therefore, Emily would have x + 2 charms.
According to the problem, their combined total is 42 charms. So, we can write an equation:
x + (x + 2) = 42
Now let's solve the equation:
2x + 2 = 42
Subtract 2 from both sides:
2x = 40
Divide both sides by 2:
x = 20
So Sara has 20 charms, and Emily has x + 2 = 20 + 2 = 22 charms.
Therefore, the correct answer is option b) Emily has 20 charms, and Sara has 22 charms.
