Last year, the volleyball team paid $5 pair for socks and $17 per pair for shorts on a total purchase of $315. This year they sp
vivado [14]

Answer:

Option E is correct.

12 pairs of socks and 15 pairs of shorts did team buy each year.

Step-by-step explanation:

Let the number of pairs of socks be x and the number pairs of shorts be y.

As per the statement:

Last year, the volleyball team paid $5 pair for socks and $17 per pair for shorts on a total purchase of $315.

⇒5x+17y = 315                   .....[1]

It is also given that: This year they spent $342 to buy the same number of socks and shorts, because the socks now cost $6 a pair and the shorts cost $18.

⇒6x + 18y = 342                   .....[2]

Multiply equation [1] by 6 both sides we get;

30x+102y = 1890                 .......[3]

Multiply equation [2] by 5 both sides we get;

30x +90y = 1710                   .....[4]

Subtract equation [4] from [3] we get;

12y =180

Divide both sides by 168 we get;

y = 15

Substitute the given values of y =15 in [1] we get;

5x+17(15) = 315

5x + 255 = 315

Subtract 255 from both sides we get;

5x = 60

Divide both sides by 5 we get;

x = 12

Therefore, 12 pairs of socks and 15 pairs of shorts did team buy each year.
