Answer:
$133.9
Step-by-step explanation:
<em>I believe the unit being used in the problem above is dollar ($).</em>
The problems above can be easily solved by using <em>multiplication operation </em>and <em>addition operation </em>afterwards.
Given: Bermuda sod = <em>$2.25 per piece</em>
Zoysia sod = <em>$3.32 per piece</em>
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
<em>It will cost Becky $133.9 to buy 20 pieces of Zoysia sod and 30 pieces of Bermuda sod.</em>

This is a tough one especially for me. I'll find out. Did you get the answer yet though?
For scientific notation, you always want 1 digits in front of the decimal.
Ex) 7.39*10^5
Move the decimal point in between the 1 and 4, or 1 place to the left.
1.435
Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.
1.435*10^1
1.435*10^1 is your final answer.
1.435*10 is the same thing also.
