Answer:
Martha can buy 7 packs of socks.
Step-by-step explanation:
Martha has $53
Shoes = $42
Socks = $1.50 each
First subtract 42 from 53 to figure out how much is left:
⇒ $53 - $42 = $11
then divide the answer by how much each pack of socks cost:
⇒ = 7.33
next, take the whole number of the answer and multiply that by $1.50 to figure how much 7 pack of socks cost:
⇒ 7 socks x $1.50 = $10.50
subtract the answer from $11 to figure out how much remains:
⇒ $11 - $10.5 = $0.50
