She. buys a pair of boots for $36 and 8 pairs of socks.
She does not use the entire amount on the gift card.
Which inequality can be used to find s, the price in
dollars of each pair of socks?
a) 70 + 8s < 36
b) 36 + 8s < 70
c) 70 - 85 < 36
d) 36 - 8s < 70

Answer 1

• Lets pairs be s
• She bought 36+8s

Now its less than $70

Hence

`\\ \tt\longmapsto 36+8s<70`

Answer 2

• b) 36 + 8s < 70

Explanation:

She used the amount:

• 36 + 8s

If this is less then the entire amount of $70, the inequality to reflect this is:

• 36 + 8s < 70

Correct choice is b
