Question

PLEASE HELP!!!

Not including tax, 14 pieces of clothing cost $107. Pants cost $12.50 and shirts cost $4.00. No other types of clothes were purchased. Which system of equations could be used to solve for the number of pants (p) and the number of shirts (s) bought?

A)
p+s=107
12.5p+4s=14

B)
p+s=14
12.5p+4s=107

C)
p+s=16.5
12.5p+4s=14

D)
16.5(p+s)=14
12.5p+4s=107

Answer 1

I believe the answer is B

Answer 2

Option B is correct.

Explanation:

Let the pants be represented by = p

Let the shirts be represented by = s

Pants cost $12.50 means 12.50p and shirts cost $4.00 means 4s

As given, 14 pieces of clothing costs the above values, so first equation becomes :
`p+s=14`

The second equation becomes as per the above scenario,
`12.50p+4s=107`
