Quan is shopping.He can buy 2 pairs of pants and 1 shirt for $79.85 (before tax is added). He can buy 1 pair of pants and 2 shirts for $69.85.(before tax is added). To figure out how much a shirt of a pair of pants cost, you must be able to write the equations. What equations descibe this problem?
a)s + p = $79.85 and s - p = $69.85
b)s + 2p = $79.85 and s + p = $69.85
c)s - p = $79.85 and s + p = $69.85
d)s + 2p = $79.85 and 2s + p = $69.85
and the answer i picked was b

To solve this problem, let's assign variables to represent the cost of a pair of pants and a shirt. Let's say "p" represents the cost of a pair of pants, and "s" represents the cost of a shirt.
From the information given, we know that Quan can buy 2 pairs of pants and 1 shirt for a total cost of $79.85. This can be written as the equation: 2p + s = $79.85.
We also know that Quan can buy 1 pair of pants and 2 shirts for a total cost of $69.85. This leads to the equation: p + 2s = $69.85.
So the correct set of equations to solve this problem is option b) s + 2p = $79.85 and s + p = $69.85.
To solve these equations, you can use methods like substitution or elimination. In this case, using the elimination method, we can multiply the second equation by -2 and add it to the first equation to eliminate "s". This will give us the equation 3p = $120. Then, solving for "p", we find that a pair of pants costs $40.
To find the cost of a shirt, substitute the value of "p" into either of the original equations. For example, using the first equation, we get s + 2(40) = $79.85. Simplifying this equation gives us s = $79.85 - $80 = -$0.15.
However, since the cost of a shirt cannot be negative, there might be an error in the original information or calculations. So it seems there might not be a valid solution to the problem based on the given information.
