Question

Tina uses a $50 gift certificate to buy a pair of pajamas for $17.97, a necklace for $25.49, and 3 pairs of socks that each cost the same amount. Tina has to pay $0.33 because the gift certificate does not cover the total cost of all the items. How much does each pair of socks cost?

Answer 1

do 50 minus 17.97 then take that answer and subtract 25.49 and divide that answer by 3 which equals $2.18. $2.18 is the answer 

Answer 2

Answer: $2.18

Explanation:

Total amount spent by Tina= $50+$0.33=$50.33

Cost of pajamas=$17.97

Cost of necklace=$25.49

Cost of 3 pairs of socks=
`\$50.33-\$17.97-\$25.49`

`=50.33-(17.97+25.49)\\=50-43.46=\$6.54`

Thus, cost of 3 pairs of socks= $6.54

Now, cost of 1 pair of socks=
`(6.54)/(3)=\$2.18`

Hence the cost of each pair of socks =$2.18
