Kurt can buy one pound of nails for $3.55 how many pounds of nails can kurt buy for $12 round to the nearest hundredth.

He can buy 3.38 pounds of nails and stay under 12 dollars.

Step-by-step explanation:

We need to write an inequality to solve this problem

total amount >= cost per pound of nails * pounds of nails

The total amount is 12  and the cost per pound of nails is 3.55

Let p = number of pounds of nails

12>= 3.55 * p

Divide each side by 3.55

12/3.55 >=3.55p/3.55

3.38028169 >=p

We round to the nearest hundredth

He can buy 3.38 pounds of nails and stay under 12 dollars.
