Answer:
The number of pounds of bananas sold are <u>50</u> and the number of pounds of raspberries sold are <u>37</u>.
Step-by-step explanation:
Given:
Charlotte runs a farm stand that sells bananas and raspberries.
Each pound of bananas sells for $3.25 and each pound of raspberries sells for $1.75.
Charlotte sold 13 more pounds of bananas than pounds of raspberries and made $227.25 altogether.
Now, tot find the number of pounds of bananas sold and the number of pounds of raspberries sold.
Let the number of pounds of raspberries be
Let the number of pounds of bananas be
Selling price of each pound of raspberries = $1.75.
Selling price of each bananas = $3.25.
Total price of bananas and raspberries sold = $227.25.
Now, we put an equation to get the number of pounds of bananas sold and the number of pounds of raspberries sold:
<em>Subtracting both sides by 42.25 we get:</em>
<em /><em />
<em>Dividing both sides by 5 we get:</em>
<u>The number of pounds of raspberries = 37 pounds.</u>
Substituting the value of :
<u>The number of pounds of bananas = 50.</u>
Therefore, the number of pounds of bananas sold are 50 and the number of pounds of raspberries sold are 37.
Answer:
Step-by-step explanation:
We have been given that a polynomial function models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.
In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:
The zeroes of this polynomial occur when either or
.
The equation have no real solutions. Therefore, the only time when the roller coaster is at the ground is at
