Bermuda sod cost 2.25 per piece. Zoysia sod cost 3.32 per piece. Becky wants to put 20 pieces of Zoysia on a bare spot under a tree and 30 pieces of Bermuda in her front yard. How much will it cost her?

$133.9

Step-by-step explanation:

I believe the unit being used in the problem above is dollar ($).

The problems above can be easily solved by using multiplication operation and addition operation afterwards.

Given: Bermuda sod = $2.25 per piece

           Zoysia sod = $3.32 per piece

Let's solve for the cost of buying the Zoysia sod.

20 pieces x $3.32 per piece = $45 dollars

The total cost of the Zoysia sod that Becky will buy is $66.4.

Next, let's solve for the cost of buying the Bermuda sod.

30 pieces x $2.25 per piece = $67.5

The total cost of the Bermuda sod that Becky will buy is $67.5.

Let's get the total cost.

$66.4 + $67.5 = $133.9

It will cost Becky $133.9 to buy 20 pieces of Zoysia sod and 30 pieces of Bermuda sod.
