On a farm, a cow eats about 24 pounds of hay per day. If hay costs $1.55 per pound, how much does it cost to feed a cow each day?

$37.20 per day

Step-by-step explanation:

Since $1.55 is the amount per pound you would multiply 1.55 x 24 to get 37.5 and since it is money you would add a zero at the end, it would look like so,

$37.20

Hope that helps and have a great day!
