Question

Suzy buys 2 shirts and 2 pairs of pants for 42 dollars at the store. Annette buys 3 shirts and 1 pair of pants for 37 dollars.

Answer 1

Answer:

The correct option is 1.

Step-by-step explanation:

Let the cost price of one shirt be s and the cost price of one pair pants is p.

Suzy buys 2 shirts and 2 pairs of pants for 42 dollars at the store. It means

$2s+2p=42$

Annette buys 3 shirts and 1 pair of pants for 37 dollars. It means

$3s+1p=37$

The system of equation is defined as

$3s+p=37$             .... (1)

$2s+2p=42$             .... (2)

On solving (1) and (2), we get

p=13, s=8

Therefore the correct option is 1.

Answer 2

2s+2p = 42,
3s+p = 37,

2 shirts at 8 = 16,
2 pants at 13 = 26.

Hope this helps.
