Answer:
A 12
B 30 lost
Step-by-step explanation:
Answer:
Jenna sold 280 boxes, Becca sold 105 boxes.
Step-by-step explanation:
For every 3 boxes B sold, J sold 8 boxes and ended with a total of 385 boxes sold.
3b+8j=385
From how the question is asked, we can assume that each round of sales would equal 11 total sales. (3b+8j=11)
Knowing the sales take place in intervals of 11, we can solve the problem by doing 385/11.
385/11=35
Finally, with 35 rounds of sales happening and knowing Jenna sells 8 while Becca sells 3 at each one, all that's left to do is multiply.
8x35=280
3x35=105
To be sure we can check our answer by adding them together, 280+105=385.
Answer:
1. 
2. x = 16
3. Part 1: P is the independent variable and S is the dependent variable.
Part 2: x is the independent variable and y is the dependent variable.
Step-by-step explanation:
1. To write the function notation for:
Sales tax is 7% of the total price.
Let the total price be
.
And sales tax be
.
As per the given statement:

Writing it in the function notation:

2. To find the value of x such that
and

Putting the value of 

3. To find the dependent and independent variable.
Independent variables are those whose value is not dependent on the other variable's values.
Dependent variables are dependent on the value of other variables.
In question 1:

P is the independent variable.
S is the dependent variable.
In question 2:
If we write it as follows:

x is the independent variable and y is the dependent variable.
Answer:
Step-by-step explanation:
t(35/100)=42
35t=4200
t=120
So there is a total of 120 fruit trees.
<span>A factory produced 150 tons of steel in one year. the next year, the output increased to 180 tons. Then,The percentage increase = (Final -initial) /initial *100 = (180-150)*100/150 = 20% Thus, the net percentage increase in the output is 20%</span>
