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>
Answer:
<h2>
15 oysters have been collected</h2>
Step-by-step explanation:
15/100 x 100
100 on the right hand side being the oysters she must collect and the 15% being the percentage of oysters she has collected divided by 100 which is used when finding out the percentage of numbers
Let the unknown number be 
.
Then the opposite of this unknown number will be 
.
It is given to us in the question that when this unknown number, is increased by 9, or in other words when 9 is added to this unknown number, , then this becomes 5 times it's opposite, which is .
Thus, from the given condition in the question, the equation we get is as:
We will solve this by isolating as:
Thus the required number is -1.5
