Question

On Saturday, Mrs. Armour bought 7 pairs of socks for $3 each, and a sweater for her dog for $12. Then she found a $5 bill on the sidewalk. Over the course of Saturday, what was the change in the amount of money Mrs. Armour had?

Answer 1

Think about it, she had bought 7 pairs of socks for $3 each. 7x3= 21. That's $21. Then she bought a sweater for $12. 21+12=33. Then she found $5 which means 33-5=28. So she basically spent $28.

Answer 2

Answer: The amount of is changed by $38.

Step-by-step explanation:

It is given that Mrs. Armour bought 7 pairs of socks for $3 each, and a sweater for her dog for $12.

The cost of 1 pair of socks is 3. So the cost of 7 is,

`7* 3=21`

The cost of 7 socks is $21.

She purchase 1 sweater for $12.

Total amount she spent is,

`\$21+\$12=\$33`

It means after purchasing the socks and sweater the total amount is reduced by $33.

It is given that she found a $5 bill on sidewalk. It means the total amount is increased by $5. Hence the total change in the amount is,

`\$33-\$5=\$28`

Therefore, the amount of Mrs. Armour had is reduced by $28.
